The piston further has a lateral face which is in sliding engagement with a wall of the cylinder. A first bore is provided through the wall of the cylinder for forming part of the inlet channel. A second bore is provided through the piston. The second bore has a first opening in the lateral face of the piston and a second opening in the end face of the piston. In the position of rest of the piston the first opening of the second bore is in registry with the first bore, whereby the second bore maintains communication between the first bore and the work chamber of the cylinder. There is also provided an outlet channel which maintains communication between the work chamber and the ambient atmosphere during at least one part of the work stroke.

Description

Die vorliegende Erfindung betrifft eine automatische Handfeuerwaffe gemäss dem Gattungsbegriff des unabhängigen Patentanspruches 1.The present invention relates to an automatic handgun according to the preamble of independent claim 1.

Bei automatischen Handfeuerwaffen ist es bekannt, den Druck des Treibgases für das Geschoss im Lauf zur Betätigung des Verschlusses oder von Teilen des Verschlusses zu verwenden. Zur Entnahme dieses Steuerdruckes, der immerhin bis 2000 bar betragen kann, ist im Kornträger eine Düsenanordnung vorhanden, deren Bohrung mit einer Bohrung im Lauf kommuniziert. Ein Düsenstück mit unterschiedlich ausgebildeten Nuten ist einstellbar in der Düsenanordnung vorhanden, derart, dass die dem Lauf entweichende Gasmenge durch einen von zwei unterschiedlichen Querschnitten gelangt und auf einen Kolben an einer Kolbenstange zur Betätigung des Verschlusses einwirkt.In automatic handguns, it is known to use the pressure of the propellant gas for the projectile in the barrel to actuate the breech or parts of the breech. To remove this control pressure, which can be up to 2000 bar, there is a nozzle arrangement in the grain carrier, the bore of which communicates with a bore in the barrel. A nozzle piece with differently shaped grooves is adjustable in the nozzle arrangement in such a way that the amount of gas escaping from the barrel passes through one of two different cross sections and onto one Piston acts on a piston rod to actuate the closure.

Infolge der Pulverrückstände, die mit dem Gas durch die Düsenanordnung gelangen, kann schon nach Abgabe weniger Schüsse eine starke Verschmutzung festgestellt werden. Auch arbeitet diese automatische Betätigung unterschiedlich in Abhängigkeit von der verschlossenen Munition, und insbesondere bei Abschuss von Gewehrgranaten mit Normalmunition oder Treibladungen kann der Druck stark ansteigen oder länger wirken.As a result of the powder residues that pass through the nozzle arrangement with the gas, heavy soiling can be detected after only a few shots have been fired. This automatic actuation also works differently depending on the locked ammunition, and in particular when rifle grenades are fired with normal ammunition or propellant charges, the pressure can rise sharply or appear longer.

Mittels der die Kolbenstange umfassenden Schliessfeder wird nach erfolgter Schussabgabe das Gas aus der Düsenanordnung auf demselben Weg in den Lauf zurück und ins Freie abgegeben. Eine Selbstreinigung der verschiedenen Bohrungen und Kanäle, die zum Teil noch abgewinkelt sind, kann somit nicht erfolgen.By means of the closing spring comprising the piston rod, after the shot has been fired, the gas is released from the nozzle arrangement in the same way back into the barrel and into the open. The various bores and channels, some of which are still angled, cannot be self-cleaned.

Es ist deshalb eine Aufgabe der Erfindung die oben genannten Nachteile bekannter automatischer Handfeuerwaffen zu verbessern. Insbesondere soll der Gasdruck in der Zylinder-Kolben-Anordnung nur in engen Grenzen variieren können, derart, dass der Verschlussantrieb gleichmässig und die Materialbeanspruchung gering gehalten werden können und es soll eine Selbstreinigung der Kanäle ermöglicht werden.It is therefore an object of the invention to improve the above-mentioned disadvantages of known automatic handguns. In particular, the gas pressure in the cylinder-piston arrangement should only be able to vary within narrow limits, such that the closure drive can be kept uniform and the material stress can be kept low, and the channels should be self-cleaning.

Erfindungsgemäss wird dies durch die Merkmale im kennzeichnenden Teil des unabhängigen Patentanspruches 1 erreicht.This is achieved according to the invention by the features in the characterizing part of independent claim 1.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert. Es zeigen :

  • Fig. 1 Teile der Handfeuerwaffe im Längsschnitt, mit dem Kolben in Ruhestellung, .
  • Fig. 2 einen Ausschnitt aus Fig. 1 mit dem Kolben während dem Arbeitshub,
  • Fig. 3 eine Schnittansicht der Waffe nach der Schnittlinie III-III in Fig. 1 mit einer ersten Stellung des Kolbens, und
  • Fig. 4 eine Schnittansicht gemäss der Schnittlinie IV-IV in Fig. 2.
An embodiment of the invention is explained below with reference to the drawing. Show it :
  • Fig. 1 parts of the hand gun in longitudinal section, with the piston in the rest position,.
  • 2 shows a detail from FIG. 1 with the piston during the working stroke,
  • Fig. 3 is a sectional view of the weapon along the section line III-III in Fig. 1 with a first position of the piston, and
  • 4 shows a sectional view along the section line IV-IV in FIG. 2.

Die Fig. 1 und 2 zeigen einen Ausschnitt der Waffe mit dem Kolben in zwei verschiedenen Betriebsstellungen.1 and 2 show a section of the weapon with the piston in two different operating positions.

Der Lauf 1 ist im vorderen Teil nahe an dessen Mündung mit einer radialen Bohrung 14 versehen. Im Lauf sind die Züge mit den Nuten 13 und den erhabenen Stellen 12 sichtbar. Ein Düsenstück 2 dient als Kornträger, der jedoch nicht dargestellt ist, weil er allgemein bekannt ist. Das Düsenstück 2 weist eine, zum Lauf 1 parallele Bohrung auf, in die ein Zylinder bestehend aus Zylinderrohr 50 und Einsatzhülse 22, die zugleich den Zylinderboden 18 bildet, eingesetzt ist. Das Düsenstück 2 ist mittels Stiften 15 gegen Verdrehung gegenüber dem Lauf 1 gesichert.The barrel 1 is provided in the front part close to its mouth with a radial bore 14. The trains with the grooves 13 and the raised areas 12 are visible in the course. A nozzle piece 2 serves as a grain carrier, which is not shown, however, because it is generally known. The nozzle piece 2 has a parallel to the barrel 1 Bore in which a cylinder consisting of cylinder tube 50 and insert sleeve 22, which also forms the cylinder bottom 18, is inserted. The nozzle piece 2 is secured by means of pins 15 against rotation relative to the barrel 1.

Mit der Bohrung 14 im Lauf fluchtend, weisen das Düsenstück 2 eine Bohrung 21 und das Zylinderrohr eine Bohrung 26 auf, die mit der Bohrung 14 zusammen einen Eintrittskanal zum Zylinder bilden. Die Einsatzhülse 22 ist mit einem seitlich radial abstehenden Flansch 24 versehen, der in einer Nutenpartie 52 in einem Zylinderflansch 51 am Ende des Zylinderrohres 50 drehbar gehaltert und geführt ist. Die Einsatzhülse 22 trägt auf ihrem, aus dem Zylinderrohr 50 vorstehenden Teil einen Einstellknopf 30, der zwei parallel zueinander angeordnete seitliche Flächen 30b und auf dem übrigen Umfang eine Randrierung 30a aufweist. Stirnseitig besitzt der Einstellknopf 30 einen Schlitz 30c für einen Schraubenzieher. Damit kann die Einsatzhülse 22 gegenüber dem Zylinderrohr 50 von aussen her verstellt werden. Mit einer Stellschraube 32, die in ein Gewinde 33 im Zylinderrohr 50 eingeschraubt ist, kann die Einsatzhülse 22 in zwei mit Markierungen 31 bezeichneten Lagen festgehalten werden.Aligned with the bore 14 in the barrel, the nozzle piece 2 has a bore 21 and the cylinder tube has a bore 26, which together with the bore 14 form an inlet channel to the cylinder. The insert sleeve 22 is provided with a laterally radially projecting flange 24 which is rotatably supported and guided in a groove section 52 in a cylinder flange 51 at the end of the cylinder tube 50. The insert sleeve 22 carries on its part protruding from the cylinder tube 50 an adjustment knob 30 which has two side surfaces 30b arranged parallel to one another and a border 30a on the remaining circumference. On the face side, the adjusting knob 30 has a slot 30c for a screwdriver. The insert sleeve 22 can thus be adjusted from the outside relative to the cylinder tube 50. With an adjusting screw 32, which is screwed into a thread 33 in the cylinder tube 50, the insert sleeve 22 can be held in two positions designated by markings 31.

Aus den Fig. 3 und 4 ist ersichtlich, dass die Einsatzhülse 22 zwei radiale Bohrungen 16, 17 von unterschiedlichem Durchmesser aufweist, wobei die Bohrung 16 grösser ist als die Bohrung 17. Im Düsenstück 2 sind zwei Bohrungen 19, 20 vorhanden, die seitlich des Laufes 1 ins Freie führen und deren Achsen in der gleichen Ebene senkrecht zur Laufachse liegen und sich wenigstens angenähert beim Durchstosspunkt der Zylinderrohrachse mit der genannten senkrechten Ebene schneiden.3 and 4 it can be seen that the insert sleeve 22 has two radial bores 16, 17 of different diameters, the bore 16 being larger than the bore 17. In the nozzle piece 2 there are two bores 19, 20 which are located on the side of the Guide barrel 1 into the open and its axes lie in the same plane perpendicular to the barrel axis and intersect at least approximately at the point of intersection of the cylinder tube axis with the vertical plane mentioned.

Die Achsen der Bohrungen 16 und 17 in der Einsatzhülse 22 schneiden sich ebenfalls, wenigstens annäherungsweise, beim Durchstosspunkt der Zylinderrohrachse durch diese genannte vertikale Ebene. Dabei ist der Winkel zwischen den beiden Achsen der Bohrungen 16 und 17 in der Einsatzhülse 22 halb so gross wie der Winkel zwischen den beiden Achsen der Bohrungen 19, 20 im Düsenstück 2.The axes of the bores 16 and 17 in the insert sleeve 22 likewise intersect, at least approximately, at the point of intersection of the cylinder tube axis through said vertical plane. The angle between the two axes of the bores 16 and 17 in the insert sleeve 22 is half as large as the angle between the two axes of the bores 19, 20 in the nozzle piece 2.

In dem durch das Zylinderrohr 50 und der Einsatzhülse 22 gebildeten,pneumatischen Zylinder ist ein Kolben 42 axialbeweglich eingesetzt, der starr mit einer Kolbenstange 45 verbunden ist, um die Bewegung des Kolbens 42 in üblicher Weise auf den Verschluss bzw. auf Elemente des Verschlusses zu übertragen. Dieser Kolben ist mit einer radialen Bohrung 28 versehen, dif in Fetriebslage gemäss den Figuren 1 und 3 mit dem Eintrittskanal, gebildet durch die Bohrungen 14, 21, 26 und 17, fluchtet. Eine achsiale Bohrung 29 im Kolben 42 mündet mit der Oeffnung 41 im Kolbenboden 40 in-den Zylinderraum 23.In the pneumatic cylinder formed by the cylinder tube 50 and the insert sleeve 22, a piston 42 is inserted so as to be axially movable, which is rigidly connected to a piston rod 45 in order to transmit the movement of the piston 42 in a conventional manner to the closure or to elements of the closure . This piston is provided with a radial bore 28, dif in the operating position according to Figures 1 and 3 with the inlet channel, formed by the holes 14, 21, 26 and 17, aligned. An axial bore 29 in the piston 42 opens into the cylinder space 23 with the opening 41 in the piston head 40.

Das Zylinderrohr 50 besitzt drei Bohrungen 25, 26, 27, deren Achsen ebenfalls in derselben senkrechten Ebene auf der Achse des Laufes 1 liegen und sich wenigstens angenähert im Durchstosspunkt der Zylinderrohrachse durch diese Ebene schneiden. Die Achsen von je zwei benachbarten Bohrungen 25, 26 bzw. 26, 27 schliessen gleiche Winkel ein, die übrigens gleich gross sind, wie die Winkel zwischen den Achsen der Bohrungen 16 und 17 in der Einsatzhülse 22. Demnach schneiden sich die Achsen der beiden aussenliegenden Bohrungen 25, 27 unter dem gleichen Winkel, wie die Achsen der Bohrungen 19, 20 im Düsenstück 2.The cylinder tube 50 has three bores 25, 26, 27, the axes of which likewise lie in the same vertical plane on the axis of the barrel 1 and intersect this plane at least approximately at the point of intersection of the cylinder tube axis. The axes of two adjacent bores 25, 26 and 26, 27 enclose the same angles, which are incidentally the same size as the angles between the axes of the bores 16 and 17 in the insert sleeve 22. Accordingly, the axes of the two outer ones intersect Bores 25, 27 at the same angle as the axes of the bores 19, 20 in the nozzle piece 2.

Die Bohrungen 14, 21, 26, 16 oder 17, 28 und 29 bilden zusammen einen Eintrittskanal bis in den Zylinderraum 23. Entsprechend bilden die Bohrungen 16, 26 und 19 einen ersten Austrittskanal oder die Bohrungen 17, 27 und 20 bilden einen zweiten Austrittskanal, wenn die Einsatzhülse von der Markierung II zur Markierung I im Gegenuhrzeigersinn gedreht wird.The bores 14, 21, 26, 16 or 17, 28 and 29 together form an inlet channel into the cylinder space 23. Accordingly, the bores 16, 26 and 19 form a first outlet channel or the bores 17, 27 and 20 form a second outlet channel, when the insert sleeve is turned counter-clockwise from mark II to mark I.

Die Funktionsweise wird nun nachfolgend beschrie- :The mode of operation is now described below:

Der die Patrone durch den Lauf treibende Gasdruck aus der Verbrennung des Treibladungspulvers gelangt hinter der Patrone durch die Bohrung 14 im Lauf 1 gemäss dem Pfeil A in Fig. 1 und 3 durch die Bohrung 21 in das Düsenstück 2 und weiter durch die Bohrung 26 und 17 in die radiale Bohrung 28 im Kolben 42. Das Gas verlässt den Kolben 42 durch die axiale Bohrung 29 und erzeugt im Zylinderraum 23 einen Pressdruck, durch den der Kolben 42 nach rechts in Fig. 1 verschoben wird. Nach kurzer Zeit, wenn die radiale Bohrung 28 im Kolben gegenüber der Bohrung 17 in der Einsatzhülse 22 verschoben ist wird der Gasfluss unterbrochen.The gas pressure driving the cartridge through the barrel from the combustion of the propellant powder passes behind the cartridge through bore 14 in barrel 1 according to arrow A in FIGS. 1 and 3 through bore 21 into nozzle piece 2 and further through bore 26 and 17 into the radial bore 28 in the piston 42. The gas leaves the piston 42 through the axial bore 29 and generates a pressing pressure in the cylinder space 23, by means of which the piston 42 is displaced to the right in FIG. 1. After a short time, when the radial bore 28 in the piston is displaced relative to the bore 17 in the insert sleeve 22, the gas flow is interrupted.

Damit wird erreicht, dass praktisch immer die gleiche Gasmenge unter praktisch dem gleichen Druck in den Zylinderraum 23 einströmt, um dem Kolben 42 aus der Ruhestellung den Arbeitshub zu ermöglichen.This ensures that practically always the same amount of gas flows into the cylinder space 23 under practically the same pressure in order to enable the piston 42 to move from the rest position.

Während des Arbeitshubes,gemäss Fig. 2 und 3, sind der Eintrittskanal mit den Bohrungen 14, 21, 26 und 17 und der Austrittskanal mit den Bohrungen 16, 25 und 19 über den Zylinderraum 23 miteinander verbunden, so dass die gespannten Gase im Zylinderraum 23 in Richtung des Pfeiles C aus diesem ins Freie ausströmen und gleicheitit die Bohrung 16 in der Einsatzhülse 22 reinigen.2 and 3, the inlet duct with the bores 14, 21, 26 and 17 and the outlet duct with the bores 16, 25 and 19 are connected to one another via the cylinder chamber 23, so that the strained gases in the cylinder chamber 23 In the direction of arrow C, flow out into the open and simultaneously clean the bore 16 in the insert sleeve 22.

Der Pfeil C ist strichliert eingezeichnet, weil in der in Fig. 3 dargestellten Lage des Kolbens 42 dieser Kanal verschlossen ist.The arrow C is shown in broken lines because in the position of the piston 42 shown in FIG. 3, this channel is closed.

Aus Fig. 3 ist ersichtlich, dass die Einsatzhülse 22 mit der kleineren Bohrung 17 im Eintrittskanal und mit der grösseren Bohrung 16 im Austrittskanal angeordnet ist. Diese Stellung ist bei frisch gereinigten Waffen vorzuziehen. Wird dann die Einsatzhülse in Stellung II gedreht, so liegt die grössere Bohrung 16 im Eintrittskanal und dafür die kleinere Bohrung 17 im Austrittskanal, wie dies in Fig. 2 und 4 deutlich dargestellt ist. Damit wird eine grössere Gasmenge in den Zylinderraum 23 eingeleitet, die eine grössere Oeffnungsenergie auf ein allfällig stark verschmutztes Verschlusssystem abgeben kann. In Fig. 4 ist zudem die Gasströmung durch die Pfeile A, B, D verdeutlicht.From Fig. 3 it can be seen that the insert sleeve 22 is arranged with the smaller bore 17 in the inlet channel and with the larger bore 16 in the outlet channel. This position is preferable for freshly cleaned weapons. If the insert sleeve is then rotated into position II, the larger bore 16 lies in the inlet channel and instead the smaller bore 17 in the outlet channel, as is clearly shown in FIGS. 2 and 4. Thus, a larger amount of gas is introduced into the cylinder space 23, which can release a larger opening energy to a possibly very dirty closure system. The gas flow is also illustrated in FIG. 4 by the arrows A, B, D.

Zur Zurückstellung des Kolbens 42 in die Ruhestellung dient die Schliessfeder auf der Kolbenstange 45. Wenn der Kolben den Austrittskanal verschliesst, wird das restliche Gas aus dem Zylinderraum über den Einströmkanal in den Lauf zurückgepresst.The closing spring on the piston rod 45 serves to return the piston 42 to the rest position. When the piston closes the outlet channel, the remaining gas from the cylinder chamber is pressed back into the barrel via the inflow channel.
