Description
KÄLTEMITTELVERDICHTER REFRIGERANT COMPRESSOR
TECHNISCHES GEBIETTECHNICAL AREA
Die vorliegende Erfindung bezieht sich auf einen Verdichter für hermetisch gekapselte Kleinkältemaschinen gemäß Oberbegriff des Anspruchs 1-The present invention relates to a compressor for hermetically sealed small refrigeration machines according to the preamble of claim 1-
STAND DER TECHNIKSTATE OF THE ART
Verdichter dieser Art weisen in bekannter Weise einen Zylinder mit einem Zylindergehäuse und einen in der Kolbenbohrung des Zylinders geführten Kolben zur Verdichtung eines Arbeitsmediums auf, wobei der Zylinder mit einem Zylinderkopf abgeschlossen ist. Zur Befestigung des Zylinderkopfes am Zylindergehäuse werden üblicherweise Schraubenverbindungen verwendet .Compressors of this type have, in a known manner, a cylinder with a cylinder housing and a piston guided in the piston bore of the cylinder for compressing a working medium, the cylinder being closed off with a cylinder head. Screw connections are usually used to attach the cylinder head to the cylinder housing.
Bei der Verwendung von Schraubenverbindungen zeigt sich allerdings der Nachteil, dass aufgrund der Kräfte, die über die Schrauben in das Zylindergehäuse eingeleitet werden, die zylindrische Form der Zylinderbohrung negativ beeinflusst wird. Des weiteren bedingen Schraubverbindungen stets erhöhten Montageaufwand, da zunächst die Bohrungen für die Schrauben gezielt gesetzt werden müssen, um eine optimale Zentrierung des Zylinderkopfes relativ zum Zylindergehäuse sicherzustellen. Außerdem wäre es vorteilhaft, den durch Schraubverbindungen bedingten, punktuellen Anpressdruck durch einen über die gesamte Dichtfläche konstanten Anpressdruck zu ersetzen, wodurch auch die Dichtfläche verringert werden kann. Des weiteren wäre es vorteilhaft, die Krafteinleitung der Befestigungsmittel für den Zylinderkopf am Zylindergehäuse so zu bewerkstelligen, dass sie besonders in jenen Bereichen des Zylinderkopfes vorgenommen wird, in denen auch die größten Belastungen durch die Kolbenkraft auftreten. Dadurch könnte eine Schonung des Zylinderkopfes bewirkt werden.When using screw connections, however, there is the disadvantage that the cylindrical shape of the cylinder bore is adversely affected by the forces that are introduced into the cylinder housing via the screws. Furthermore, screw connections always involve increased assembly effort, since the holes for the screws must first be placed in a targeted manner in order to ensure optimal centering of the cylinder head relative to the cylinder housing. In addition, it would be advantageous to replace the point contact pressure caused by screw connections with a contact pressure that is constant over the entire sealing surface, as a result of which the sealing surface can also be reduced. Furthermore, it would be advantageous to apply the force to the fastening means for the cylinder head on the cylinder housing in such a way that it is particularly effective in those areas of the cylinder head Cylinder head is made, in which the greatest loads from the piston force occur. This could protect the cylinder head.
AUFGABE DER ERFINDUNGOBJECT OF THE INVENTION
Es ist daher Ziel der Erfindung, den Zylinderkopf am Zylindergehäuse so zu fixieren, dass eine negative Beeinträchtigung der zylindrischen Form der Zylinderbohrung vermieden wird. Es ist weiters Ziel der Erfindung, den Montage- und Materialaufwand zu verringern, indem auf die Verwendung von Schrauben verzichtet wird. Dabei soll eine leichte Zentrierbarkeit des Zylinderkopfes relativ zum Zylindergehäuse sicher gestellt sein. Ein gleichmäßiger Anpressdruck sowie eine Verringerung der Dichtflächen und damit bei gleichbleibender Flächenpressung eine geringere Anpresskraft zur Abdichtung der Dichtflächen werden damit notwendig, wodurch die Verformungen geringer sind. Des weiteren soll die Krafteinleitung der Befestigungsmittel für den Zylinderkopf am Zylindergehäuse so bewerkstelligt werden, dass sie besonders in jenen Bereichen des Zylinderkopfes vorgenommen wird, in denen auch die größten Belastungen durch die Kolbenkraft auftreten, um so den Zylinderkopf minimal zu belasten.It is therefore the object of the invention to fix the cylinder head on the cylinder housing in such a way that a negative impairment of the cylindrical shape of the cylinder bore is avoided. It is a further object of the invention to reduce the assembly and material expenditure by dispensing with the use of screws. It should be ensured that the cylinder head can be easily centered relative to the cylinder housing. A uniform contact pressure as well as a reduction of the sealing surfaces and thus a lower contact pressure to seal the sealing surfaces are necessary with constant surface pressure, so that the deformations are less. Furthermore, the force application of the fastening means for the cylinder head to the cylinder housing is to be carried out in such a way that it is carried out particularly in those areas of the cylinder head in which the greatest loads are caused by the piston force in order to minimally load the cylinder head.
LÖSUNG DER AUFGABESOLUTION TO THE TASK
Diese Ziele werden durch die kennzeichnenden Merkmale von Anspruch 1 erreicht.These goals are achieved by the characterizing features of claim 1.
Anspruch 1 sieht hierbei vor, dass ein Befestigungselement vorgesehen ist, das den Zylinderkopf am Zylindergehäuse durch einen im Bereich der Achse der Kolbenbohrung ausgeübten Anpressdruck befestigt. Gemäß Anspruch 2 handelt es sich hierbei um eine Klemme, die den Zylinderkopf am Zylindergehäuse befestigt. Gemäß Anspruch 3 weist die Klemme einen Basisteil und Seitenteile auf, wobei der Basisteil in axialer Richtung vor dem Zylinderkopf angeordnet ist unci mithilfe des Basisteiles ein Anpressdruck auf den Zylinderkopf: in axialer Richtung ausgeübt wird, und die Seitenteile relativ zum Zylindergehäuse fest verankert sind. Der Basisteil der Klemme wird dabei in zweckmäßiger Weise so breit gewählt werden, dass er den Zylinderkopf mit gleichmäßigem Anpressdruck am Zylindergehäuse fixiert. Anspruch 4 sieht als besondere Ausgestaltung vor, dass die Seitenteile als seitlich abstehende, federnde Schenkel mit im wesentlichen L-förmicj gebogenen Endbereichen ausgebildet sind, wobei der Basisteil- am Zylinderkopf anliegt und die Verankerung der Seitenteile relativ zum Zylindergehäuse über eine Verrastung deir Endbereiche der federnden Schenkel erfolgt. Gemäß Anspruch 5 ist dabei die Klemme im wesentlichen U-förmig ausgeführt, wobei aber auch denkbar wäre, mehrere Schenkel vorzusehen. Gemäß Anspruch 6 ist der Basisteil in Richtung der Schenkel gewölbt ausgeführt, wodurch die Druckbelastbarkeit des Basisteils erhöht wird.Claim 1 provides that a fastening element is provided which fastens the cylinder head to the cylinder housing by a contact pressure exerted in the region of the axis of the piston bore. According to claim 2, this is a clamp that the cylinder head on Cylinder housing attached. According to claim 3, the clamp has a base part and side parts, the base part being arranged in the axial direction in front of the cylinder head, and with the aid of the base part a contact pressure being exerted on the cylinder head: in the axial direction, and the side parts being firmly anchored relative to the cylinder housing. The base part of the clamp will expediently be chosen so wide that it fixes the cylinder head to the cylinder housing with an even contact pressure. Claim 4 provides a particular embodiment requires that the side parts are constructed as laterally projecting, resilient legs with an essentially L-förmic j bent end portions, wherein the Basisteil- abuts the cylinder head and the anchoring of the side portions relative to the cylinder housing via a latching deir end portions of the resilient leg takes place. According to claim 5, the clamp is essentially U-shaped, but it would also be conceivable to provide several legs. According to claim 6, the base part is curved in the direction of the legs, whereby the pressure resistance of the base part is increased.
Die Verrastung kann auf unterschiedliche Weise verwirklicht werden. Gemäß Anspruch 7 erfolgt die Verrastung mithilfe von fest mit einem Trageteil des Verdichters verbundenen Lagerblöcken, wobei die Lagerblöcke jeweils über zumindest eine Kante verfügen, die von den Endbereichen der Schenkel zumindest teilweise umgriffen werden.The locking can be realized in different ways. According to claim 7, the locking takes place with the aid of bearing blocks firmly connected to a support part of the compressor, the bearing blocks each having at least one edge which is at least partially encompassed by the end regions of the legs.
Gemäß Anspruch 8 ist zur Bildung einer Verrastung vorgesehen, dass die Klemme das gesamte Zylindergehäuse umgreift, wobei das Zylindergehäuse über Kanten verfügt, die von den Endbereichen der Schenkel zumindest teilweise umgriffen werden. Somit kann auf die Verwendung von Lagerblöcken verzichtet werden. Gemäß Anspruch 9 wird die Verrastung mithilfe von Nuten im Zylindergehäuse gebildet, in die jeweils ein Endbereich der Schenkel eingreift.According to claim 8 is provided to form a latch that the clamp encompasses the entire cylinder housing, the cylinder housing having edges which are at least partially encompassed by the end regions of the legs. The use of bearing blocks can thus be dispensed with. According to claim 9, the latching formed by means of grooves in the cylinder housing, in each of which an end region of the legs engages.
Der Basisteil der Klemme muss nicht unbedingt direkt am Zylinderkopf anliegen. So ist etwa gemäß Anspruch 10 vorgesehen, dass der Basisteil eine Anpressschraube führt, die einen Anpressdruck auf den Zylinderkopf in axialer Richtung ausübt. Gemäß Anspruch 11 ist hingegen vorgesehen, dass der Basisteil direkt am Zylinderkopf anliegt und die Seitenteile an fest mit einem Trageteil des Verdichters verbundenen Lagerblöcken verankert sind, wobei zumindest einer der Seitenteile als Schraubverbindung zwischen Basisteil und Lagerblock ausgeführt ist. In beiden Varianten kann durch verändertes Anziehen der Schraube ein variabler Anpressdruck des Zylinderköpfes am Zylindergehäuse erreicht werden.The base part of the clamp does not necessarily have to lie directly on the cylinder head. For example, it is provided according to claim 10 that the base part guides a pressure screw, which exerts a pressure on the cylinder head in the axial direction. According to claim 11, however, it is provided that the base part rests directly on the cylinder head and the side parts are anchored to bearing blocks which are fixedly connected to a support part of the compressor, at least one of the side parts being designed as a screw connection between the base part and the bearing block. In both variants, a variable contact pressure of the cylinder head on the cylinder housing can be achieved by changing the tightening of the screw.
Anspruch 12 sieht eine alternative Ausführungsform des erfindungsgemäßen Befestigungselements vor, bei der das Befestigungselement als Spannbügel ausgebildet ist.

Fig. 1 zeigt eine perspektivische Darstellung einer ersten Ausführungsform der relativen Anordnung von Zylinderkopf 1, Zylindergehäuse 4 und des erfindungsgemäßen Befestigungselements, das als Klemme 2 ausgeführt ist. Hierbei sind die einzelnen Komponenten lediglich schematisch dargestellt, so wird der Zylinderkopf 1 in der Regel als Baugruppe ausgeführt sein, die insbesondere eine Ventilplatte (in den Fig. 1 bis 9 und 14 bis 22 nicht dargestellt) enthält. Auch eine solche Baugruppe ist im folgenden von der Bezeichnung „Zylinderkopf 1" umfasst. Für ein Verständnis der gegenständlichen Erfindung ist aber lediglich entscheidend, dass der Zylinderkopf 1 eine Stirnfläche 10 als Kontaktfläche zum Zylindergehäuse 4 bzw. zur Ventilplatte 16 und eine Anpressfläche 11 als Kontaktfläche zum Basisteil 5 der Klemme 2 aufweist. Innerhalb des Zylindergehäuses 4 ist ein Kolben (in den Fig. 1 bis 22 nicht gezeigt) zur Verdichtung eines Arbeitsmediums geführt. Der Zylinderkopf 1 kann dabei an der Ventilplatte 16 anliegen oder sie gänzlich umgreifen. Im ersten Fall ist unmittelbar ersichtlich, dass ein von der Klemme 2 auf den Zylinderkopf 1 ausgeübter Anpressdruck sich unmittelbar auf die VentilplatteFig. 1 shows a perspective view of a first embodiment of the relative arrangement of cylinder head 1, cylinder housing 4 and the fastening element according to the invention, which is designed as a clamp 2. Here, the individual components are only shown schematically, so the cylinder head 1 will generally be designed as an assembly, which in particular contains a valve plate (not shown in FIGS. 1 to 9 and 14 to 22). Such an assembly is also encompassed in the following by the designation “cylinder head 1”. However, for an understanding of the present invention, it is only decisive that the cylinder head 1 has an end face 10 as a contact surface to the cylinder housing 4 or to the valve plate 16 and a contact surface 11 as a contact surface to the base part 5 of the clamp 2. A piston (not shown in FIGS. 1 to 22) is guided inside the cylinder housing 4 to compress a working medium. The cylinder head 1 can rest against the valve plate 16 or completely encompass it. In the first case it is immediately apparent that a contact pressure exerted by the clamp 2 on the cylinder head 1 is directly on the valve plate
16 überträgt und sie an das Zylindergehäuse 4 anpresst. Im zweiten Fall werden innerhalb des Zylinderkopfes 1 Stege 21 vorgesehen sein, die an der Ventilplatte 16 anliegen und eine16 transmits and presses them against the cylinder housing 4. In the second case 1 webs 21 are provided within the cylinder head, which abut the valve plate 16 and one
Übertragung des von der Klemme 2 ausgeübten Anpressdruckes sicherstellen. Solche Stege 21 können aber auch vorgesehen sein, wenn der Zylinderkopf 1 an der Ventilplatte 16 anliegt, wie etwa aus Fig. 13 ersichtlich ist. Hierbei wird angemerkt, dass die Ventilplatte 16 in den Fig. 1 bis 9 und 14 bis 22 nicht unmittelbar ersichtlich, aber selbstverständlich vorgesehen ist. Sie wird gemäß der Darstellungen in den Fig. 1 bis 9 und 14 bis 22 vom Zylinderkopf 1 vollkommen umgriffen, sodass sie in diesen Darstellungen nicht sichtbar ist. DieEnsure transmission of the contact pressure exerted by terminal 2. Such webs 21 can, however, also be provided if the cylinder head 1 rests on the valve plate 16, as can be seen, for example, from FIG. 13. It is noted here that the valve plate 16 in FIGS. 1 to 9 and 14 to 22 is not immediately apparent, but is of course provided. According to the representations in FIGS. 1 to 9 and 14 to 22, it is completely encompassed by the cylinder head 1, so that it is not visible in these representations. The
Fig. 10 und 11 zeigen hingegen ein Explosionsbild, in der die10 and 11, however, show an exploded view in which the
Ventilplatte 16 zu sehen ist. Die Form und die Zentrierung derValve plate 16 can be seen. The shape and centering of the
Ventilplatte 16 im Zylindergehäuse 4 werden aber später beschrieben, zunächst soll die Fixierung der Ventilplatte 16 relativ zum Zylindergehäuse mithilfe der Klemme 2 näher beschrieben werden.Valve plate 16 in the cylinder housing 4 will be described later, however, first the fixing of the valve plate 16 relative to the cylinder housing will be described in more detail using the clamp 2.
Erfindungsgemäß erfolgt die Fixierung des Zylinderkopfes 1 relativ zum Zylindergehäuse 4 etwa mittels einer Klemme 2. Die Klemme 2 weist in einer Ausführungsform einen Basisteil 5 sowie seitlich abstehende, federnde Schenkel 6 auf, wobei gemäß einer bevorzugten Ausführungsform der Basisteil 5 in Richtung der Schenkel 6 gewölbt ausgeführt ist. Dadurch wird die Biegesteifigkeit und somit die Druckbelastbarkeit des Basisteils 5 erhöht. Im montierten Zustand ist der Basisteil 5 in Bezug auf den Zylinderkopf 1 so ausgerichtet, dass die Wölbung des Basisteils 5 mit ihrer konvexen Seite am Zylinderkopf 1 anliegt. Der Basisteil 5 der Klemme 2 wird dabei in zweckmäßiger Weise so breit gewählt werden, dass er den Zylinderkopf 1 mit gleichmäßigem Anpressdruck am Zylindergehäuse 4 fixiert.According to the invention, the cylinder head 1 is fixed relative to the cylinder housing 4, for example by means of a clamp 2. In one embodiment, the clamp 2 has a base part 5 and resilient legs 6 projecting laterally, the base part 5 being arched in the direction of the legs 6 according to a preferred embodiment is executed. This increases the bending stiffness and thus the compressive strength of the base part 5. In the assembled state, the base part 5 is aligned with respect to the cylinder head 1 in such a way that the curvature of the base part 5 lies against the cylinder head 1 with its convex side. The base part 5 of the terminal 2 is appropriately chosen so wide that it fixed the cylinder head 1 to the cylinder housing 4 with even contact pressure.
Gemäß der in den Fig. 1 bis 6 gezeigten Ausführungsformen weist die Klemme 2 zwei Schenkel 6 auf und ist somit im wesentlichen U-förmig ausgebildet. Es wäre aber auch denkbar, dass die Klemme 2 über mehrere Schenkel 6 verfügt. Bevorzugt sind die Schenkel 6 so ausgeführt, dass sie sich für eine Verrastung eignen. Bei der erfindungsgemäßen Ausführung des Verdichters wird dies erreicht, indem die Endbereiche 7 der Schenkel 6 im wesentlichen L-förmig ausgebildet sind, wie noch näher ausgeführt werden wird.According to the embodiments shown in FIGS. 1 to 6, the clamp 2 has two legs 6 and is thus essentially U-shaped. It would also be conceivable that the clamp 2 has several legs 6. The legs 6 are preferably designed such that they are suitable for latching. In the embodiment of the compressor according to the invention, this is achieved in that the end regions 7 of the legs 6 are essentially L-shaped, as will be explained in greater detail.
Gemäß der Ausführungsform von Fig. 1 sind des weiteren Lagerblöcke 3 vorgesehen, wobei die Lagerblöcke 3 jeweils über zumindest eine Kante 12 verfügen, die von den Endbereichen 7 der Schenkel 6 zumindest teilweise umgriffen werden, sodass die Klemme 2 an den Lagerblöcken 3 einhakt und somit eine Verrastung gebildet wird, die eine sichere Verankerung der Seitenteile 6 sicherstellt. Die Art der Verrastung ist dabei besonders deutlich in Fig. 2 ersichtlich. Die Lagerblöcke 3 können etwa am Zylindergehäuse 4 angeformt sein, sie können aber auch als separate Bauteile ausgeführt sein, wie dies in Fig. 1 angedeutet ist. Dabei sind die Lagerblöcke 3 nicht am Zylindergehäuse 4 befestigt, sondern an einem Trageteil 9, das Teil des Verdichters ist und jedenfalls so ausgeführt ist, dass eine zuverlässige Verrastung der Klemme 2 und somit eine sichere Fixierung des Zylinderkopfes 1 relativ zum Zylindergehäuse 4 gewährleistet ist. Durch die Verwendung von Lagerblöcken 3 wird auch die Krafteinleitung zur Fixierung des Zylinderkopfes 1 relativ zum Zylindergehäuse 4 von der Kolbenbohrung entkoppelt.According to the embodiment of FIG. 1, further bearing blocks 3 are provided, the bearing blocks 3 each having at least one edge 12 which are at least partially encompassed by the end regions 7 of the legs 6, so that the clamp 2 hooks onto the bearing blocks 3 and thus a catch is formed, which ensures secure anchoring of the side parts 6. The type of latching can be seen particularly clearly in FIG. 2. The bearing blocks 3 can be formed approximately on the cylinder housing 4, but they can also be designed as separate components, as is indicated in FIG. 1. The bearing blocks 3 are not attached to the cylinder housing 4, but to a support part 9, which is part of the compressor and is in any case designed so that a reliable locking of the terminal 2 and thus a secure fixation of the cylinder head 1 relative to the cylinder housing 4 is ensured. The use of bearing blocks 3 also decouples the force introduction for fixing the cylinder head 1 relative to the cylinder housing 4 from the piston bore.
Eine weitere Ausführungsform der Verrastung ist in den Fig. 3 und 4 dargestellt. Hierbei ist zur Bildung einer Verrastung vorgesehen, dass die Klemme 2 das gesamte Zylindergehäuse 4 umgreift, wobei das Zylindergehäuse 4 über Kanten 13 verfügt, die von den Endbereichen 7 der Schenkel 6 zumindest teilweise umgriffen werden. Somit kann auf die Verwendung von Lagerblöcken 3 verzichtet werden. Die Art der Verrastung im Rahmen dieser Ausführungsform ist besonders deutlich in Fig. 4 ersichtlich. Auch auf diese Art ist eine sichere Verankerung der Seitenteile 6 sichergestellt.Another embodiment of the latching is shown in FIGS. 3 and 4. This is to form a latch provided that the clamp 2 encompasses the entire cylinder housing 4, the cylinder housing 4 having edges 13 which are at least partially encompassed by the end regions 7 of the legs 6. Thus, the use of bearing blocks 3 can be dispensed with. The type of latching in the context of this embodiment can be seen particularly clearly in FIG. 4. Secure anchoring of the side parts 6 is also ensured in this way.
In den Fig. 5 und 6 ist eine weitere Ausführungsform der Verrastung dargestellt. Die Verrastung wird hier mithilfe von Nuten 8 im Zylindergehäuse 4 gebildet, in die jeweils ein Endbereich 7 der Schenkel 6 eingreift. Hierzu ist die Ausführungsform gemäß Fig. 15 vergleichbar, wo die Seitenteile 6 am Zylindergehäuse 4 angeformt sind und im Bereich der Achse der Kolbenbohrung eine Öffnung bilden. In diese Öffnung kann etwa mithilfe eines Nut- und Federsystems der Basisteil 5 eingesetzt werden, wobei der Basisteil 5 als starres Element ausgeführt ist.5 and 6, a further embodiment of the latching is shown. The latching is formed here with the aid of grooves 8 in the cylinder housing 4, in each of which an end region 7 of the legs 6 engages. 15, where the side parts 6 are integrally formed on the cylinder housing 4 and form an opening in the region of the axis of the piston bore. The base part 5 can be inserted into this opening, for example with the aid of a tongue and groove system, the base part 5 being designed as a rigid element.
Die Fig. 7 zeigt eine Ausführungsform einer Klemme 2, bei der der Basisteil 5 nicht direkt am Zylinderkopf 1 anliegt, sondern eine Anpressschraube 14 zur axialen Krafteinleitung vorgesehen ist. Die Anpressschraube 14 wird vom Basisteil 5 geführt, wobei der Basisteil 5 im Führungsbereich mit einem entsprechenden Gegengewinde ausgestattet ist. Ein Anziehen der Anpressschraube 14 erzeugt somit aufgrund der sicheren Verankerung der Seitenteile 6 der Klemme 2 einen zunehmenden Anpressdruck des Zylinderkopfes 1 am Zylindergehäuse 4. Dadurch kann der Anpressdruck variiert werden. Wie aus der Fig. 7 auch zu sehen ist, ist bei einer solchen Ausführungsform die Klemme 2 nicht U-förmig ausgebildet, sondern kann vielmehr V-förmig gestaltet werden. Fig. 16 zeigt eine ähnliche Ausführungsform, bei der allerdings der Basisteil 5 der Klemme 2 direkt am Zylinderkopf 1 anliegt. Eine zu Fig. 7 vergleichbare Ausführungsform ist auch in Fig. 8 gezeigt, wobei sich die lediglich die Art der Verankerung der Seitenteile 6 an den Lagerblöcken 3 unterscheidet. Gemäß Fig. 8 weisen die Lagerblöcke 3 jeweils Schlitze auf, die den jeweiligen Lagerblock 3 queren und zur Aufnahme eines Seitenteiles 6 dienen. Durch L-förmig gebogene Endbereiche 7 der Seitenteile 6 kann wiederum die Verankerung der Seitenteile 6 verbessert werden.FIG. 7 shows an embodiment of a clamp 2, in which the base part 5 does not rest directly on the cylinder head 1, but a pressure screw 14 is provided for the axial introduction of force. The pressure screw 14 is guided by the base part 5, the base part 5 being equipped with a corresponding counter thread in the guide area. Tightening the contact screw 14 thus creates an increasing contact pressure of the cylinder head 1 on the cylinder housing 4 due to the secure anchoring of the side parts 6 of the clamp 2. As a result, the contact pressure can be varied. As can also be seen from FIG. 7, in such an embodiment the clamp 2 is not U-shaped, but rather can be V-shaped. 16 shows a similar embodiment, in which, however, the base part 5 of the clamp 2 lies directly on the cylinder head 1. An embodiment comparable to FIG. 7 is also shown in FIG. 8, the only difference being the type of anchoring of the side parts 6 on the bearing blocks 3. 8, the bearing blocks 3 each have slots that cross the respective bearing block 3 and serve to receive a side part 6. The anchoring of the side parts 6 can in turn be improved by means of L-shaped bent end regions 7 of the side parts 6.
Eine weitere Ausführungsform des erfindungsgemäßen Befestigungselements ist in der Fig. 18 gezeigt. Hier sind die Seitenteile 6 der Klemme 2 durch Schrauben 28 direkt an den Lagerblöcken 3 befestigt.Another embodiment of the fastening element according to the invention is shown in FIG. 18. Here the side parts 6 of the clamp 2 are fastened directly to the bearing blocks 3 by screws 28.
Die Fig. 9 zeigt eine perspektivische Darstellung einer weiteren Ausführungsform der relativen Anordnung von Zylinderkopf 1, Zylindergehäuse 4 und der erfindungsgemäßen Klemme 2, bei der der Basisteil 5 der Klemme 2 direkt am Zylinderkopf 1 anliegt. Ein Seitenteil 6 ist dabei aber als Schraubverbindung 15 zwischen Basisteil 5 und einem Lagerblock 3 ausgeführt, wodurch ein variabler Anpressdruck des Zylinderköpfes 1 am Zylindergehäuse 4 erreicht werden kann.FIG. 9 shows a perspective illustration of a further embodiment of the relative arrangement of cylinder head 1, cylinder housing 4 and the clamp 2 according to the invention, in which the base part 5 of the clamp 2 lies directly on the cylinder head 1. A side part 6 is designed as a screw connection 15 between the base part 5 and a bearing block 3, as a result of which a variable contact pressure of the cylinder head 1 on the cylinder housing 4 can be achieved.
Anstatt der Schraubenverbindungen 15 können aber auch Hakenähnliche Verbindungen vorgesehen sein, wie dies etwa in der Fig. 17 dargestellt ist. Hier ist die Verbindung durch Haltestifte 26 mit endseitigen Köpfen 27 gegeben, die an ihrer einen Seite in einen den Lagerblock 3 querenden Schlitz einhaken und an ihrer anderen Seite in einen entsprechenden Schlitz im Seitenteil 6 der Klemme 2.Instead of the screw connections 15, hook-like connections can also be provided, as is shown, for example, in FIG. 17. Here, the connection is provided by retaining pins 26 with end heads 27 which hook on one side into a slot crossing the bearing block 3 and on the other side into a corresponding slot in the side part 6 of the terminal 2.
Eine weitere Ausführungsform des er indungsgemäßen Befestigungselements ist in den Fig. 14, 19, 21 und 22 gezeigt. Das Befestigungselement ist hier als Spannbügel 24 ausgeführt, der auf einer Seite in einem am Lagerblock 3 angeordneten Lager 29 einrastet und auf der anderen Seite durch eine Zugverbindung kraftbeaufschlagt wird. In Fig. 19 ist etwa deutlich erkennbar, wie der Endbereich einesA further embodiment of the fastening element according to the invention is shown in FIGS. 14, 19, 21 and 22. The fastening element is designed here as a clamping bracket 24, which is on one side in a on the bearing block 3rd arranged bearing 29 engages and on the other side is acted upon by a train connection. In Fig. 19 it can be clearly seen, for example, how the end region of a
Seitenteiles 6 T-förmig ausgebildet ist und in ein Lager 29 einrastet. Der andere Seitenteil 6 ist dabei am zweitenSide part 6 is T-shaped and engages in a bearing 29. The other side part 6 is on the second
Lagerblock 3 mittels einer Schraube 28 angeschraubt. In Fig.Bearing block 3 screwed by means of a screw 28. In Fig.
14 ist wiederum der zweite Seitenteil 6 durch einen Haltestift14 is in turn the second side part 6 by a retaining pin
26, wie anhand der Fig. 17 beschrieben, am Lagerblock 3 befestigt. Wie in Fig. 21 dargestellt ist, kann die26, as described with reference to FIG. 17, attached to the bearing block 3. As shown in Fig. 21, the
Befestigung des zweiten Seitenteiles 6 auch über einen etwas abgewandelten Haltestift 26 erfolgen, bei dem ein Endbereich einen Querbolzen 30 aufweist, der in einem entsprechend konkav ausgeführten Endbereich 31 eines Seitenteiles 6 der Klemme 2 gelagert ist. Fig. 22 zeigt schließlich eine Ausführungsform eines Spannbügels 24, bei dem ein Spannelement 32 von einem entsprechend konkav ausgeführten Endbereich 31 einesFastening of the second side part 6 also take place via a somewhat modified retaining pin 26, in which one end region has a transverse bolt 30 which is mounted in a correspondingly concave end region 31 of a side part 6 of the clamp 2. 22 finally shows an embodiment of a tensioning bracket 24, in which a tensioning element 32 has a correspondingly concave end region 31
Seitenteiles 6 aufgenommen wird. Das Spannelemente 32 ist wiederum an einem Lagerblock 3 befestigt.Side part 6 is added. The clamping element 32 is in turn attached to a bearing block 3.
In Fig. 20 ist schließlich eine Ausführungsform des erfindungsgemäßen Befestigungselements gezeigt, bei der es als biegeelastisches Befestigungselement 25, etwa als Seil oder Draht 25, ausgeführt ist. Das Seil bzw. der Draht 25 wird zwischen den Lagerblöcken 3 eingespannt, wobei zur besseren Führung des Seils bzw. Drahtes 25 der Zylinderkopf 1 mit einer ihn diametral querenden Nut 33 ausgestattet sein kann, in der das Seil bzw. der Draht 25 eingelegt wird. Das Seil 25 kann etwa ein Stahlseil 25 sein.Finally, FIG. 20 shows an embodiment of the fastening element according to the invention, in which it is designed as a flexurally elastic fastening element 25, for example as a rope or wire 25. The rope or wire 25 is clamped between the bearing blocks 3, and for better guidance of the rope or wire 25, the cylinder head 1 can be equipped with a groove 33 diametrically crossing it, in which the rope or wire 25 is inserted. The rope 25 can be a steel rope 25, for example.
Die oben erwähnte Ventilplatte 16 (in den Fig. 1 bis 9 und 14 bis 22 nicht dargestellt) , ist in der Regel Bestandteil der hier als Zylinderkopf 1 bezeichneten Baugruppe und ist üblicherweise am Zylindergehäuse 4 mittels Schraubverbindungen befestigt. Die Stirnfläche 10 des Zylinderkopfes 1 umgreift diese Ventilplatte 16 oder liegt an der Ventilplatte 16 an. Da bei der erfindungsgemäßen Befestigung des Zylinderkopfes 1 amThe above-mentioned valve plate 16 (not shown in FIGS. 1 to 9 and 14 to 22) is generally part of the assembly referred to here as cylinder head 1 and is usually fastened to the cylinder housing 4 by means of screw connections. The end face 10 of the cylinder head 1 engages around this valve plate 16 or lies against the valve plate 16. There in the attachment of the cylinder head 1 according to the invention
Zylindergehäuse 4 auf Schraubverbindungen verzichtet wird, ist es vorteilhaft, auch die Ventilplatte 16 ohne Verwendung vonCylinder housing 4 is dispensed with screw connections, it is advantageous to also use the valve plate 16 without
Schraubverbindungen am Zylindergehäuse 4 zu befestigen. Das kann etwa dadurch erreicht werden, indem die Ventilplatte 16 in eine stufenförmige Bohrung 17 im Zylindergehäuse 4 zumindest teilweise versenkt wird. Ist die Ventilplatte 16 scheibenförmig ausgebildet, so kann ein radialer Fortsatz 18 der Ventilplatte 16 vorgesehen sein, der in eine entsprechende radiale Einkerbung 19 im Zylindergehäuse 4 eingreift und eineFasten screw connections on the cylinder housing 4. This can be achieved, for example, by at least partially sinking the valve plate 16 into a step-shaped bore 17 in the cylinder housing 4. If the valve plate 16 is disc-shaped, a radial extension 18 of the valve plate 16 can be provided, which engages in a corresponding radial notch 19 in the cylinder housing 4 and one

Ventilplatte 16 eine radiale Einkerbung aufweisen, in die ein radial abstehender Fortsatz des Zylindergehäuses 4 eingreift.Valve plate 16 have a radial notch into which a radially projecting extension of the cylinder housing 4 engages.
Eine Verdrehung der Ventilplatte 16 in der stufenförmigen Bohrung 17 während des Betriebes des Verdichters kann aber auch ohne einen solchen Fortsatz 18 bzw. ohne Einkerbung unterbunden werden. Wie etwa in der Fig. 11 angedeutet ist, kann der Zylinderkopf 1 auch eine Ausnehmung 22 etwa zur Aufnahme eines Saugschalldämpfers (in Fig. 11 nicht dargestellt) aufweisen. Der hier angeordnete Saugschalldämpfer kann nun so geformt sein, dass er teilweise in eine Bohrung 20 der Ventilplatte 16 eingreift, sodass wiederum eine Verdrehung der Ventilplatte 16 verhindert wird. In Fig. 11 sind des weiteren Dichtungsringe 23 dargestellt.A rotation of the valve plate 16 in the step-shaped bore 17 during the operation of the compressor can also be prevented without such an extension 18 or without a notch. As is indicated, for example, in FIG. 11, the cylinder head 1 can also have a recess 22, for example for receiving a suction muffler (not shown in FIG. 11). The suction muffler arranged here can now be shaped such that it partially engages in a bore 20 in the valve plate 16, so that rotation of the valve plate 16 is again prevented. 11 also shows sealing rings 23.
Die Fig. 12 zeigt eine SchnittZeichnung der Anordnung von Zylindergehäuse 4, Ventilplatte 16 und dem Zylinderkopf 1 gemäß der Ausführungsform von Fig. 10. Hier ist insbesondere ersichtlich, dass die Stirnfläche 10 des Zylinderkopfes 1 an der Ventilplatte 16 anliegt und ebenfalls in der stufenförmigen Bohrung 17 teilweise versenkt ist. Die Fig. 13 zeigt eine Schnittzeichnung der Anordnung von Zylindergehäuse 4, Ventilplatte 16 und dem Zylinderkopf 1 gemäß der Ausführungsform von Fig. 11, wobei insbesondere ersichtlich ist, dass der Zylinderkopf 1 Stege 21 aufweisen kann, die für zusätzlichen Anpressdruck des Zylinderkopfes 1 an die Ventilplatte 16 sorgen.FIG. 12 shows a sectional drawing of the arrangement of the cylinder housing 4, valve plate 16 and the cylinder head 1 according to the embodiment of FIG. 10. Here it can be seen in particular that the end face 10 of the cylinder head 1 lies against the valve plate 16 and also in the stepped bore 17 is partially sunk. 13 shows a sectional drawing of the arrangement of cylinder housing 4, valve plate 16 and cylinder head 1 according to FIG Embodiment of FIG. 11, wherein it can be seen in particular that the cylinder head 1 can have webs 21 which provide additional contact pressure of the cylinder head 1 against the valve plate 16.
In der Fig. 23 ist eine perspektivische Darstellung einer weiteren Ausführungsform der relativen Anordnung von Zylinderkopf 1, Ventilplatte 16 und Zylindergehäuse 4 dargestellt, bei der ein Verriegelungskörper 34 vorgesehen ist. Hierbei weisen die Ventilplatte 16 als auch das Zylindergehäuse 4 jeweils eine radiale Einkerbung 35, 36 auf, in die bei radialer Ausrichtung der Einkerbung 35 der Ventilplatte 16 mit der Einkerbung 36 des Zylindergehäuses 4 ein Verriegelungskörper 34 einsetzbar ist. Der Verriegelungskörper ist in der Fig. 23 als längliches, stabförmiges Element 34 dargestellt, es sind aber auch andere Ausführungsformen denkbar, sofern sie eine Verdrehung der Ventilplatte 16 bzw. des Zylinderkopfes 1 im Zylindergehäuse 4 unterbinden. Des weiteren kann auch der Zylinderkopf 1 eine radiale Einkerbung 37 aufweisen, in die bei überlagernder Ausrichtung der Einkerbung 35 der Ventilplatte 16 mit der Einkerbung 37 des Zylinderkopfes 1 der Verriegelungskörper 34 einsetzbar ist.23 shows a perspective illustration of a further embodiment of the relative arrangement of cylinder head 1, valve plate 16 and cylinder housing 4, in which a locking body 34 is provided. Here, the valve plate 16 and the cylinder housing 4 each have a radial notch 35, 36, into which a locking body 34 can be inserted when the notch 35 of the valve plate 16 is radially aligned with the notch 36 of the cylinder housing 4. The locking body is shown in FIG. 23 as an elongated, rod-shaped element 34, but other embodiments are also conceivable, provided they prevent the valve plate 16 or the cylinder head 1 from rotating in the cylinder housing 4. Furthermore, the cylinder head 1 can also have a radial notch 37, into which the locking body 34 can be inserted when the notch 35 of the valve plate 16 is overlapping with the notch 37 of the cylinder head 1.
Die Krafteinleitung bzw. der Anpressdruck des erfindungsgemäßen Befestigungselements 2, 24, 25 für den Zylinderkopf 1 am Zylindergehäuse 4 wird in diesen Ausführungsbeispielen jeweils so bewerkstelligt, dass sie besonders in jenen Bereichen des Zylinderkopfes 1 vorgenommen wird, in denen auch die größten Belastungen durch die Kolbenkraft auftreten, also im Bereich der Achse der Kolbenbohrung. Wie dieser Anpressdruck des Befestigungselements 2, 24, 25 durch seine unterschiedlichen Komponenten erzeugt wird, wird in den Fig. 14 bis 22 durch die eingezeichneten Kraftvektoren illustriert. Der durch dasThe force application or the contact pressure of the fastening element 2, 24, 25 according to the invention for the cylinder head 1 on the cylinder housing 4 is accomplished in each of these exemplary embodiments in such a way that it is carried out particularly in those areas of the cylinder head 1 in which the greatest loads are caused by the piston force occur, i.e. in the area of the axis of the piston bore. How this contact pressure of the fastening element 2, 24, 25 is generated by its different components is shown in FIGS. 14 to 22 by the illustrated force vectors illustrated. The one through that
Befestigungselement 2, 24, 25 im Bereich der Achse derFastening element 2, 24, 25 in the area of the axis of the
Kolbenbohrung ausgeübte Anpressdruck entspricht dabei in bevorzugter Weise einer axialen Anpresskraft von 1000 N bis 10000 N, vorzugsweise 3000 N.The contact pressure exerted on the piston bore preferably corresponds to an axial contact force of 1000 N to 10000 N, preferably 3000 N.
Wie aus den Fig. 1 bis 23 ersichtlich ist, wird bei der erfindungsgemäßen Ausführungsform eines Verdichters erreicht, dass der Zylinderkopf 1 am Zylindergehäuse 4 ohne Beeinträchtigung der zylindrischen Form des Zylinders fixiert werden kann. Des weiteren wird Montage- und Materialaufwand verringert, da auf die Verwendung von Schrauben verzichtet werden kann. Dabei wird eine leichte Zentrierbarkeit des Zylinderkopfes 1 relativ zum Zylindergehäuse 4 sicher gestellt und ein gleichmäßiger Anpressdruck des Zylinderkopfes 1 am Zylindergehäuse 4 sowie eine Verringerung der Dichtfläche 10 ermöglicht. Des weiteren wird die Krafteinleitung des Befestigungselements für den Zylinderkopf 1 am Zylindergehäuse 4 so bewerkstelligt, dass sie besonders in jenen Bereichen des Zylinderkopfes 1 vorgenommen wird, in denen auch die größten Belastungen durch die Kolbenkraft auftreten. Dadurch wird der Zylinderkopf 1 bestmöglich geschont und er kann auch kleiner ausgeführt werden. Die Befestigung des Zylinderkopfes 1 am Zylindergehäuse 4 ist außerdem leicht lösbar und stellt aber dennoch einen sicheren Verschluss des Zylinders sicher. As can be seen from FIGS. 1 to 23, it is achieved in the embodiment of a compressor according to the invention that the cylinder head 1 can be fixed on the cylinder housing 4 without impairing the cylindrical shape of the cylinder. Furthermore, assembly and material costs are reduced, since the use of screws can be dispensed with. This ensures that the cylinder head 1 can be easily centered relative to the cylinder housing 4 and enables a uniform contact pressure of the cylinder head 1 on the cylinder housing 4 and a reduction in the sealing surface 10. Furthermore, the force application of the fastening element for the cylinder head 1 to the cylinder housing 4 is accomplished in such a way that it is carried out particularly in those areas of the cylinder head 1 in which the greatest loads occur due to the piston force. This protects the cylinder head 1 as well as possible and it can also be made smaller. The attachment of the cylinder head 1 to the cylinder housing 4 is also easily detachable, but still ensures a secure closure of the cylinder.
