"Ölfilter mit Absteuerventil im Reinölrohr""Oil filter with shut-off valve in the clean oil pipe"
Die Neuerung betrifft einen Ölfilter nach dem Oberbegriff des Anspruchs 1.The innovation relates to an oil filter according to the preamble of claim 1.
Derartige Ölfilter sind aus der Praxis bekannt.Such oil filters are known from practice.
Das Absteuerventil dient dazu, Druckspitzen im Ölkreislauf abzufangen. Zusätzlich können sogenannte Filterumgehungsventile vorgesehen sein, die bei einem verstopften Filterelement das Filtermedium umgehen. Während die Filterumgehungsventile innerhalb des Innenraums des Filters, häufig innerhalb des Filterelementes angeordnet sind, ist bei den Absteuerventilen häufig eine aufwendige Montage erforderlich, da diese von außen in das Gehäuse des Filters eingebracht werden müssen. Abgesehen davon, dass an diesen Stellen eine spezielle Bearbeitung des üblicherweise preisgünstig aus einem Druckguss-Werkstoff hergestellten Filtergehäuses bzw. Filtersockels erforderlich ist, ist ggf. auch die Gießform im Druckgusswerk aufwendig, da hier eine zusätzliche Schieberrichtung vorgesehen sein muss.The shut-off valve is used to absorb pressure peaks in the oil circuit. In addition, so-called filter bypass valves can be provided, which bypass the filter medium if the filter element is clogged. While the filter bypass valves are located inside the filter, often inside the filter element, the shut-off valves often require complex assembly, as they have to be inserted into the filter housing from the outside. Apart from the fact that special machining of the filter housing or filter base, which is usually made inexpensively from a die-cast material, is required at these points, the casting mold in the die-casting plant may also be complex, as an additional slide direction must be provided here.
Zudem ergibt sich die Schwierigkeit, dass ein vergleichsweise großer Bauraum unterhalb des Innenraumes des Ölfilters vorgesehen sein muss, in welchem nämlich das Absteuerventil angeordnet ist, sodass die konstruktive Freiheit eines Herstellers von Verbrennungsmotoren eingeschränkt ist, wo der Ölfilter angeordnet werden kann.In addition, there is the difficulty that a comparatively large installation space must be provided below the interior of the oil filter, in which the shut-off valve is arranged, so that the design freedom of a manufacturer of internal combustion engines is limited as to where the oil filter can be arranged.
Der Neuerung liegt die Aufgabe zugrunde, einen gattungsgemäßen Ölfilter dahingehend zu verbessern, dass dieser möglichst preisgünstig hergestellt werden kann und einen möglichst geringen Platzbedarf aufweist, sodass die konstruktive Freiheit zur Anordnung dieses Ölfilters möglichst groß ist.The innovation is based on the task of improving a generic oil filter so that it can be manufactured as inexpensively as possible and requires as little space as possible, so that the design freedom for the arrangement of this oil filter is as great as possible.
Diese Aufgabe wird durch einen Ölfilter mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by an oil filter having the features of claim 1.
Die Neuerung schlägt mit anderen Worten vor, das Absteuerventil im Reinölrohr anzuordnen. Auf diese Weise wird ein separater Sitz für diese Ventilbaugruppe nicht erforderlich, der ansonsten im Filtergehäuse geschaffen werden müsste. Es ist daher keine Bearbeitung von Druckgussteilen des Filtergehäuses bzw. Filtersockels erforderlich, um das Absteuerventil unterzuIn other words, the innovation proposes arranging the shut-off valve in the clean oil pipe. This way, a separate seat for this valve assembly is not required, which would otherwise have to be created in the filter housing. Therefore, no machining of die-cast parts of the filter housing or filter base is required in order to accommodate the shut-off valve.
bringen. Weiterhin kann das Druckgusswerk auf einen zusätzlichen Schieber in der Druckgussform verzichten.Furthermore, the die-casting plant can dispense with an additional slide in the die-casting mold.
Weiterhin ergibt sich der Vorteil, dass bei Dichtprüfung des Ab-Steuerventils lediglich das Reinölrohr nachgebessert oder ausgetauscht werden muss. Wird bei Absteuerventilen, die im Filtergehäuse oder Filtersockel angeordnet sind, eine Undichtigkeit festgestellt, so muss entweder das Filtergehäuse bzw. der Filtersockel, beides nachfolgend gemeinsam als Filtergehäuse angesprochen, aufwendig demontiert werden oder stellt ein verAnother advantage is that when testing the shut-off valve for leaks, only the clean oil pipe needs to be repaired or replaced. If a leak is detected in shut-off valves located in the filter housing or filter base, either the filter housing or the filter base, both referred to jointly as the filter housing, must be dismantled at great expense or a
gleichsweise teures Verlustteil dar.represents an equally expensive loss component.
Ein weiterer Vorteil ergibt sich daraus, dass kein zusätzlicher Bauraum im Bereich des Filtergehäuses geschaffen werden muss, da das Reinölrohr ohnehin vorgesehen ist. Zudem wirdA further advantage is that no additional installation space needs to be created in the area of the filter housing, since the clean oil pipe is already provided. In addition,
kein separater Ventilsitz benötigt, da dieser Ventilsitz unmittelbar vom Reinölrohr gebildet werden kann, sodass der Ölfilter mit weniger Bauteilen herstellbar ist.No separate valve seat is required, since this valve seat can be formed directly from the clean oil pipe, so that the oil filter can be manufactured with fewer components.

In den Zeichnungen ist mit 1 allgemein ein Ölfilter bezeichnet mit einem Filtergehäuse 2, welches einen Innenraum 3 aufweist, in welchem ein auswechselbares Filterelement 4 angeordnet ist.In the drawings, 1 generally designates an oil filter with a filter housing 2 which has an interior space 3 in which a replaceable filter element 4 is arranged.
Das Filtergehäuse 2 weist einen abnehmbaren Schraubdeckel 5The filter housing 2 has a removable screw cap 5
auf, sodass das Filterelement 4 regelmäßig gewartet und ausgetauscht werden kann. Das Filtergehäuse 2 schließt als ein gemeinsames Bauteil auch einen Filtersockel 6 ein, wobei in dem Filtersockel 6 drei Ölkanäle vorgesehen sind:so that the filter element 4 can be regularly maintained and replaced. The filter housing 2 also includes a filter base 6 as a common component, with three oil channels being provided in the filter base 6:
Durch einen Einlasskanal 7 gelangt ungefiltertes Rohöl in den Innenraum 3. Es tritt durch das Filtermedium in das Innere des Filterelementes 4 und gelangt durch ein Reinölrohr 8 und dessen Auslassöffnung in einen Auslasskanal 9 und von dort zu den Schmierstellen.Unfiltered crude oil enters the interior 3 through an inlet channel 7. It passes through the filter medium into the interior of the filter element 4 and passes through a clean oil pipe 8 and its outlet opening into an outlet channel 9 and from there to the lubrication points.
Wenn der Ölfilter 1 gewartet wird, der Schraubdeckel 5 also abgeschraubt wird, wird das Reinölrohr 8, belastet durch eine bei 10 angedeutete Druckfeder, nach oben gedrückt, dabei öffnet eine Dichtung 11 und Öl aus dem Innenraum 3 kann in einenWhen the oil filter 1 is serviced, i.e. the screw cap 5 is unscrewed, the clean oil pipe 8 is pushed upwards, loaded by a pressure spring indicated at 10, thereby opening a seal 11 and oil from the interior 3 can flow into a

Daher kann mit konstruktiv geringem Aufwand am unteren Ende des Reinölrohrs 8 ein Absteuerventil 14 vorgesehen sein. Dabei bildet das Reinölrohr 8 einen Ventilsitz 15 aus, dem ein kappenartiger Ventilkörper 16 anliegt. Der Ventilkörper 16 wird durch die Wirkung einer Feder 17 gegen den Ventilsitz 15 gepresst,Therefore, with little structural effort, a shut-off valve 14 can be provided at the lower end of the clean oil pipe 8. The clean oil pipe 8 forms a valve seat 15, against which a cap-like valve body 16 rests. The valve body 16 is pressed against the valve seat 15 by the action of a spring 17,
sodass das Absteuerventil 14 geschlossen ist und eine Ablassöffnung 18, die im Reinölrohr 8 ausgestaltet ist, gegenüber dem übrigen Inneren des Reinölrohres 8 abgedichtet ist.so that the shut-off valve 14 is closed and a drain opening 18, which is formed in the clean oil pipe 8, is sealed from the remaining interior of the clean oil pipe 8.
Fig. 2 zeigt, wie bei unzulässig hohem Druck innerhalb desFig. 2 shows how excessive pressure within the
Reinölrohres 8 der Ventilkörper 16 gegen die Wirkung der Feder 17 nach unten bewegt worden ist und durch den Abstand vom Ventilsitz 15 nun das Absteuerventil 14 geöffnet ist. Reinöl kann aus dem Reinölrohr 8 durch das Absteuerventil 14 und die Ablassöffnung 18 in den Ablasskanal 12 gelangen, wobei derClean oil pipe 8, the valve body 16 has been moved downwards against the action of the spring 17 and the clearance from the valve seat 15 now opens the shut-off valve 14. Clean oil can flow from the clean oil pipe 8 through the shut-off valve 14 and the drain opening 18 into the drain channel 12, whereby the
Kreislauf des Öls im übrigen unbeeinflusst bleibt, d. h., ungereinigtes Öl gelangt durch den Einlasskanal 7 in den Innenraum 3, wird gefiltert und gelangt durch das Reinölrohr 8 in den Auslasskanal 9.The oil circuit remains otherwise unaffected, i.e. uncleaned oil enters the interior 3 through the inlet channel 7, is filtered and enters the outlet channel 9 through the clean oil pipe 8.
Bei dem dargestellten Ausführungsbeispiel ist das Reinölrohr 8 gleichzeitig auch als Stützdom im Innenraum 3 ausgebildet, wo es das Filterelement 4 gegen ein Kollabieren sichert.In the embodiment shown, the clean oil pipe 8 is simultaneously designed as a support dome in the interior space 3, where it secures the filter element 4 against collapse.

Das Reinölrohr kann in mehrere Abschnitte untergliedert sein, von denen ggf. ein fester Abschnitt das Absteuerventil 14 aufweist, während andere Abschnitte mit bestimmten Filterbauteilen gemeinsam beweglich sind, wie vorstehend ausgeführt.The clean oil pipe can be divided into several sections, of which a fixed section may have the shut-off valve 14, while other sections are movable together with certain filter components, as explained above.
