Der Deckel ist mittels einer Schraube am Filtergehäuse befestigbar, wobei die Schraube in ihrem Gewindebereich eine Verbindung zwischen dem Innenraum des Filtergehäuses und dem dritten Kanal in der Einbaulage verschließt. Beim Herausschrauben der Schraube wird diese Verbindung geöffnet, so daß das Schmieröl vor dem Wechsel des Filtereinsatzes zwangsläufig aus dem Filtergehäuse abfließt.The cover can be attached to the filter housing by means of a screw, the screw establishing a connection between the interior space in its threaded area of the filter housing and the third channel in the installation position. When unscrewing the screw will open this connection, so that the lubricating oil before the change of the filter insert inevitably flows out of the filter housing.

Diese in der DE-PS 25 55 420 beschriebene zwangsläufige Entleerung des Filtergehäuses ist auf Filter b#eschränkt, bei denen ein Filterwechsel durch Herausnahme und Einsetzen von Filtereinsätzen aus bzw. in das Filtergehäuse von oben erfolgt. Der Erfindung liegt die Aufgabe zugrunde, eine zwangsläufige Entleerung des Filtergehäuses beim Filterwechsel auch bei anderen Filterausbildungen mit einfachen #itteln zu erreichen.This inevitable emptying described in DE-PS 25 55 420 of the filter housing is limited to filters, where a filter change by removing and inserting filter inserts from or into the filter housing done from above. The invention is based on the object of an inevitable emptying of the filter housing when changing the filter, even with other filter designs with simple #means to achieve.

Die Aufgabe ist erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst.The object is according to the invention by the in the characterizing part of claim 1 specified features solved.

Die erfindungsgemäße Lösung ermöglicht auch bei sogenannten Wegwerf-Patronen, bei denen das Filtergehäuse und der Filtereinsatz als Baueinheit ausgeführt sind, einen Filterwechsel mit einfachen Mitteln ohne Verlust an Schmieröl durch Auslaufen ins Freie oder Verbleiben im Filtergehäuse.The solution according to the invention enables so-called disposable cartridges, in which the filter housing and the filter insert are designed as a structural unit, a filter change with simple means without loss of lubricating oil due to leakage into the open air or remaining in the filter housing.

Durch die im Anspruch 2 angegebene Weiterbildung der Erfindung wird erreicht, daß beim Abschrauben der Baueinheit sowohl das Reinöl wie das Schmutzöl aus dieser in einen gemeinsamen Kanal abfließen, ohne daß Schmutzöl über den ersten Kanal zu den Schmierstellen der Brennkraftmaschine gelangen kann.By the specified in claim 2 development of the invention is achieved that when unscrewing the unit, both the pure oil and the dirty oil from this flow into a common channel without dirt oil over the first Channel can reach the lubrication points of the internal combustion engine.

Die Ausgestaltung gemäß dem Anspruch 3 gewährleistet mit einfachen Mitteln einen sicheren Verschluß des dritten Kanals bei aufgeschraubter Baueinheit und ein sicheres Öffnen dieses Kanals beim Abschrauben der Baueinheit.The configuration according to claim 3 ensured with simple Means a secure closure of the third channel when the structural unit is screwed on and a safe opening of this channel when unscrewing the unit.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels wird der Erfindungsgegenstand im folgenden näher erläutert.Based on an embodiment shown in the drawing the subject matter of the invention is explained in more detail below.

Eine aus einem Filtergehäuse 1 und einem Filtereinsatz 2 bestehende Baueinheit 3 ist auf ein Zwischengehäuse 4 aufgeschraubt, das an eine nicht dargestellte Brennkraftmaschine angeschraubt ist. Das Filtergehäuse 1 bildet zum Zwischengehäuse 4 hin einen Boden 5, in den ein rohrförmiger Ansatz 6 des Zwischengehäuses 4 mit einem außenliegenden Schraubgewinde 7 hineinragt, auf das ein innen liegendes Gegengewinde 8 als Teil des Bodens 5 aufgeschraubt ist. Eine radial außen liegende Ringdichtung 9 zwischen dem Filtergehäuse 1 und dem Zwischengehäuse 4 dichtet die Verbindung gegen den Verlust von Schmieröl nach außen ab.One consisting of a filter housing 1 and a filter insert 2 Unit 3 is screwed onto an intermediate housing 4, which is attached to a not shown Internal combustion engine is screwed on. The filter housing 1 forms the intermediate housing 4 towards a bottom 5, in which a tubular extension 6 of the intermediate housing 4 with an external screw thread 7 protrudes, onto which an internal mating thread 8 is screwed on as part of the bottom 5. A ring seal located radially on the outside 9 between the filter housing 1 and the intermediate housing 4 seals the connection against the loss of lubricating oil to the outside.

Das Zwischengehäuse 4 wird in seiner Länge von drei Kanälen durchsetzt. Ein erster Kanal 10 dient der Zuführung von Schmutzöl zum Filtereinsatz 2, ein zweiter Kanal 11 dient der Abführung von Reinöl zu den Schmierstellen der Brennkraftmaschine und ein dritter Kanal 12 dient der Abführung des Schmieröls in das Kurbelgehäuse der Brennkraftmaschine bei einer Entleerung des Filtergehäuses 1.The intermediate housing 4 is penetrated in its length by three channels. A first channel 10 is used to supply dirty oil to the filter insert 2, a second Channel 11 is used to discharge pure oil to the lubrication points of the internal combustion engine and a third channel 12 serves to discharge the lubricating oil into the crankcase of the internal combustion engine when the filter housing 1 is emptied.

Das durch den ersten Kanal 10 zugeführte Schmutzöl strömt über einen Ringraum 13 zwischen dem Boden 5 und dem Zwischengehäuse 4 sowie Öffnungen 14 im Boden 5 in einen Schmutzölraum 15 und gelangt von dort durch den Filtereinsatz 2 in den innen gelegenen Reinölraum 16. Das gereinigte Schmieröl fließt von dort über die Mittenöffnung 17 des rohrförmigen Ansatzes 6, die in diesem Bereich die gemeinsame Führung des zweiten und dritten Kanals bildet, in den zweiten Kanal 11. In den dritten Kanal 12 kann trotz seiner Lage unterhalb des zweiten Kanals 11 bei der gezeigten Einbaulage der Baueinheit 3 kein Schmieröl gelangen, da er durch einen Verschlußkörper 18 verschlossen ist, der von einer von dem Gegengewinde 8 abragenden federnden Zunge 19 über eine Stange 20 auf den Einlaß des dritten Kanals 12 gedrückt wird.The dirty oil supplied through the first channel 10 flows over a Annular space 13 between the bottom 5 and the intermediate housing 4 and openings 14 in the Bottom 5 into a dirty oil chamber 15 and from there passes through the filter insert 2 into the clean oil room 16 located inside. The cleaned lubricating oil flows over from there the central opening 17 of the tubular extension 6, which in this area is the common Guiding the second and third channel forms into the second channel 11. In the third Channel 12 can despite its location below the second channel 11 in the case of the one shown In the installation position of the structural unit 3, no lubricating oil can get through, as it passes through a closure body 18 is closed by a resilient tongue protruding from the mating thread 8 19 is pressed via a rod 20 onto the inlet of the third channel 12.

Wird für einen Filterwechsel die Baueinheit 3 abgeschraubt, so wird der Druck der Zunge 19-auf den Verschlußkörper 18 aufgehoben und diese hebt unter dem Einfluß einer Druckfeder 21, die sich einerseits am Zwischengehäuse 4 und andererseits an einem Bund 22 an der Stange 20 abstützt, von dem Einlaß des dritten Kanals 12 ab, so daß das Schmieröl aus dem Reinölraum 16 über den dritten Kanal 12 abfließen kann. Gleichzeitig stellen Öffnungen 23, die das Gegengewinde 8 durchsetzen, jedoch in Einbaulage der Baueinheit 3 durch das Schraubgewinde 7 abgedeckt sind, beim Abschrauben der Baueinheit 3 eine Verbindung zwischen dem Schmutzölraum 15 und dem dritten Kanal 12 her, so daß auch das Schmieröl aus dem Schmutzölraum 15 abfließen kann. Es wird somit eine zwangsläufige Entleerung des gesamten Filtergehäuses 1 beim Abschrauben der Baueinheit 3 erreicht. Ein Austritt von Schmieröl ins Freie wird dadurch verhindert, daß die Öffnungen 14 durch Rückschlagventile 24 verschließbar sind, die einen Rückfluß von Schmieröl aus dem Schmutzölraum 15 in den Ringraum 13 verhindern - Leerseite -If the structural unit 3 is unscrewed for a filter change, then the pressure of the tongue 19-on the closure body 18 is lifted and this lifts under the influence of a compression spring 21 on the one hand on the intermediate housing 4 and on the other hand supported on a collar 22 on the rod 20, from the inlet of the third channel 12 so that the lubricating oil flows out of the clean oil chamber 16 via the third channel 12 can. At the same time, however, make openings 23 which penetrate the mating thread 8 are covered in the installation position of the structural unit 3 by the screw thread 7 when unscrewing of the structural unit 3 a connection between the dirty oil chamber 15 and the third channel 12 so that the lubricating oil can also flow out of the dirty oil chamber 15. It will thus a inevitable emptying of the entire filter housing 1 reached when unscrewing the structural unit 3. A leak of lubricating oil into the open is thereby prevented that the openings 14 can be closed by check valves 24 are that a backflow of lubricating oil from the dirty oil chamber 15 in the annulus 13 prevent - blank page -
