Die Figur 1 zeigt eine Kraftfahrzeugbrennkraftmaschine 15 mit einem erfindungsgemäßen ölfilter in einer schematischen Darstellung. Die Kraftfahrzeugbrennkraftmaschine 15 ist als ein Verbrennungsmotor ausgebildet und dazu vorgesehen, durch Verbrennen eines Luft-Brennstoffgemischs ein Antriebsmoment zu erzeugen, mittels dem ein Kraftfahrzeug antreibbar ist. Dazu weist die Brennkraftmachine zumindest ein Brennkraftmaschinengehäuse 16 auf, das zumindest einen Zylinder ausbildet, in dem ein beweglicher Kolben angeordnet ist, der seine axiale Bewegung über ein Pleuel in eine Rotation einer Kurbelwelle umwandelt. Zur Schmierung und Kühlung des Zylinders und anderen Bauteilen weist die Kraftfahrzeugbrennkraftmaschine 15 einen ölkreislauf auf. Zur Förderung des Be- triebsmittels weist die Kraftfahrzeugbrennkraftmaschine 15 eine nicht näher dargestellte Betriebsmittelpumpe auf. Die Betriebsmittelpumpe ist mechanisch über einen Kettentrieb angetrieben. Grundsätzlich ist es auch denkbar, dass die Betriebsmittelpumpe elektrisch betrieben ist. 1 shows a motor vehicle internal combustion engine 15 with an oil filter according to the invention in a schematic representation. The motor vehicle internal combustion engine 15 is designed as an internal combustion engine and is provided to generate a combustion torque by means of which a motor vehicle can be driven by burning an air-fuel mixture. For this purpose, the internal combustion engine has at least one internal combustion engine housing 16, which forms at least one cylinder, in which a movable piston is arranged, which converts its axial movement via a connecting rod into a rotation of a crankshaft. For lubrication and cooling of the cylinder and other components, the motor vehicle internal combustion engine 15 has an oil circuit. To promote the driving means, the motor vehicle internal combustion engine 15 on a resource pump, not shown. The operating fluid pump is mechanically driven by a chain drive. In principle, it is also conceivable that the operating medium pump is electrically operated.
Zur Reinigung des in dem Ölkreislauf zirkulierenden Betriebsmittels weist die Kraftfahrzeugbrennkraftmaschine 15 einen ölfilter 10 auf, der in dem ölkreislauf eingebunden ist. Der ölfilter 10 umfasst ein starres Filtergehäuse 1 1. Das Filtergehäuse 1 1 ist als ein längliches Rohr ausgebildet. Eine Länge des Filtergehäuses 1 1 ist dabei um ein Vielfaches größer als ein Durchmesser des Filtergehäuses 1 1. Das starre Filtergehäuse 1 1 weist eine gekrümmte Kontur auf. Das Filtergehäuse 1 1 ist durch die gekrümmte Kontur an eine Kontur der Kraftfahrzeugbrennkraftmaschine 15 angepasst. Das Filtergehäuse 11 ist als getrennt von dem Brennkraftmaschinengehäuse 16 ausgebildetes Gehäuse ausgebildet. Dabei ist das Filtergehäuse 1 1 als ein längliches Rohr mit gekrümmter Kontur ausgebildet. Das Filtergehäuse 1 1 ist aus einem starren Kunststoffschlauch hergestellt und mittels zumindest einem, dem Fachmann als sinnvoll erscheinenden Verbindungselement fest mit dem Brennkraftmaschinengehäuse 16 verbunden. Grundsätzlich ist es auch denkbar, dass das Filtergehäuse 1 1 aus einem anderen, dem Fachmann als sinnvoll erscheinenden Material, wie beispielsweise einem Metall, ausgebildet ist. Grundsätzlich ist es auch denkbar, dass das Filtergehäuse 1 1 einstückig mit dem Brennkraftmaschinengehäuse 16 ausgebildet ist. Dabei ist das als ein längliches Rohr mit gekrümmter Kontur ausgebildete Filtergehäuse 1 1 als ein Hohlraum innerhalb des Brennkraftmaschinengehäuses 16 ausgebildet. Bei einer Herstellung des Brennkraftmaschinengehäuses 16, beispielsweise durch ein Gussverfahren, wird das Filtergehäuse 1 1 in das Brennkraftmaschinengehäuse 16 eingebracht. For cleaning the circulating in the oil circuit equipment, the motor vehicle internal combustion engine 15 has an oil filter 10 which is integrated in the oil circuit. The oil filter 10 comprises a rigid filter housing 1 1. The filter housing 1 1 is formed as an elongated tube. A length of the filter housing 1 1 is thereby greater by a multiple than a diameter of the filter housing 1 1. The rigid filter housing 1 1 has a curved contour. The filter housing 1 1 is adapted by the curved contour to a contour of the motor vehicle engine 15. The filter housing 11 is formed as a housing formed separately from the engine housing 16. In this case, the filter housing 1 1 is formed as an elongated tube with a curved contour. The filter housing 1 1 is made of a rigid plastic tube and firmly connected by means of at least one, the expert appears appropriate connecting element with the engine housing 16. In principle, it is also conceivable that the filter housing 11 is formed from another material that appears appropriate to a person skilled in the art, such as, for example, a metal. In principle, it is also conceivable that the filter housing 1 1 is integrally formed with the engine housing 16. In this case, the filter housing 1 1 formed as an elongate tube with a curved contour is designed as a cavity within the engine housing 16. In a production of the engine housing 16, for example by a casting process, the filter housing 1 1 is introduced into the engine housing 16.
Das Filtergehäuse 1 1 erstreckt sich von einem unteren Bereich 17 des Brennkraftmaschinengehäuses 16 bis zu einem oberen Bereich 18 des Brennkraftmaschinengehäuses 16. Dabei reicht das Filtergehäuse 1 1 fast über eine gesamte Höhe des Brennkraftmaschinengehäuses 16. Grundsätzlich ist natürlich auch eine andere, dem Fachmann als sinnvoll erscheinende Orientierung des Filtergehäuses 1 1 denkbar. Das Filtergehäuse 1 1 umfasst zwei Anschlüsse 13, 14, über die verschiedene Bauteile der Kraftfahrzeugbrennkraftmaschine 15 und eines Antriebsstrangs mit dem Betriebsmittel versorgt werden. Die Anschlüsse 13, 14 sind dazu vorgesehen, dass Verbindungsleitungen an sie angeschlossen werden, um das Betriebsmittel von dem ölfilter 10 an die entsprechenden Bauteile zu leiten. Grundsätzlich ist es auch denkbar, dass, insbesondere in der Ausgestaltung in der das Filtergehäuse 1 1 einstückig mit dem Brennkraftmaschinengehäuse 16 ausgebildet ist, die Anschlüsse direkt als Ölbohrungen ausgebildet sind, die das Betriebsmittel direkt dem entsprechenden Bauteil zuführen. The filter housing 1 1 extends from a lower portion 17 of the engine housing 16 to an upper portion 18 of the engine housing 16. In this case, the filter housing 1 1 extends almost over an entire height of the engine housing 16. Basically, of course, another, the expert makes sense Apparent orientation of the filter housing 1 1 conceivable. The filter housing 1 1 comprises two terminals 13, 14, are supplied via the various components of the motor vehicle internal combustion engine 15 and a drive train with the resources. The ports 13, 14 are provided to connect connecting lines to them to direct the operating fluid from the oil filter 10 to the corresponding components. In principle, it is also conceivable that, in particular in the embodiment in which the filter housing 1 1 formed integrally with the engine housing 16 is that the connections are formed directly as oil holes, which supply the equipment directly to the corresponding component.
An einem unteren Ende bildet das Filtergehäuse 11 einen Anschluss 19 aus. An den An- schluss 19 ist eine Betriebsmittelversorgungsleitung 20 angebracht. Die Betriebsmittelversorgungsleitung 20 leitet das Betriebsmittel direkt von der Betriebsmittelpumpe oder einem zwischengeschalteten Betriebsmittelkühler zu dem Anschluss 19 und damit in den ölfilter 10. An einem oberen Ende bildet das Filtergehäuse 1 1 einen Verschluss 21 aus, über den der ölfilter 10 verschlossen werden kann. At a lower end, the filter housing 11 forms a connection 19. At the connection 19, a resource supply line 20 is attached. The operating medium supply line 20 directs the operating medium directly from the operating medium pump or an intermediate operating cooler to the connection 19 and thus into the oil filter 10. At an upper end, the filter housing 11 forms a closure 21, via which the oil filter 10 can be closed.
Zur Filtration des Betriebsmittels weist der ölfilter 10 ein Filter 12 auf. Der Filter 12 ist dazu vorgesehen, während einer Montage die gekrümmte Kontur des Filtergehäuses 1 1 anzunehmen. Der Filter 12 umfasst ein elastisches Filtermaterial 22, das dazu vorgesehen ist, sich an eine Kontur des Filtergehäuses 11 anzupassen. Das Filtermaterial 22 erstreckt sich dabei über die gesamte Länge des Filtergehäuses 1 1. Das Filtermaterial 22 besteht dabei aus einem Filtergewebe, das beispielsweise aus einem Fließ, einem Papier oder einem anderen, dem Fachmann als sinnvoll erscheinenden Filtergewebe ausgebildet ist. Grundsätzlich ist auch eine Kombination aus mehreren Filtergeweben denkbar. Das Filtermaterial 22 des Filters 12 bildet einen Schlauch aus. Dadurch schließt das Filtermaterial 22 einen radial innenliegenden ersten Ölraum 23 radial nach außen ab. Das Filtermaterial 22 trennt den ersten radial innenliegenden Ölraum 23 von einem zweiten, radial außerhalb des Filtermaterials 22 liegenden zweiten Ölraum 24 ab. Der zweite Ölraum 24 wird von dem Filtermaterial 22 und einer Innenwandung des Filtergehäuses 1 1 begrenzt. In dem ersten ölraum 23 strömt ungefiltertes Betriebsmittel. Strömt das Betriebsmittel durch das Filtermaterial 22 aus dem ersten ölraum 23 in den zweiten Ölraum 24 wird das Betriebsmittel durch das Filtermaterial 22 gefiltert und dadurch gereinigt. Das Betriebsmittel in dem zweiten Ölraum 24 ist von groben Partikeln und kleinen Schmutzpartikeln befreit. So kann das Betriebsmittel keinen Schaden in den Bauteilen auslösen in die es zur Schmierung und/oder Kühlung geleitet wird. Das Filtermaterial 22 bildet eine biegsame Geometrie aus. Dazu weist das Filtermaterial 22 eine Vielzahl von über seine Länge verteilte, nicht näher dargestellte Falten auf. Die Falten verlaufen dabei entlang eines Um- fangs des als Schlauch ausgebildeten Filtermaterials.

In einem montierten Zustand des Filters 12 ist das Rückschlagventil 25 in dem Anschluss 19 für die Betriebsmittelversorgungsleitung 20 angeordnet. Das Betriebsmittel kann so von der Betriebsmittelversorgungsleitung 20 ausschließlich in den ersten, radial innenliegenden ölraum 23 des Filters strömen. Dabei kann das Rückschlagventil 25 als ein Flatterventil oder als ein anderes, dem Fachmann als sinnvoll erscheinendes Rückschlagventil ausgebildet sein. The filter 12 comprises a check valve 25, which is attached to one of the resource pump end facing the filter 12. The check valve 25 is attached to a lower end of the filter 12. The check valve 25 prevents backflow of the operating medium from the filter 12 in the direction of the operating medium pump. In a mounted state of the filter 12, the check valve 25 is disposed in the port 19 for the resource supply line 20. The operating medium can thus flow from the operating medium supply line 20 exclusively into the first radially inner oil space 23 of the filter. In this case, the check valve 25 may be formed as a flutter valve or as another, the expert appears useful sense check valve.
Zum Verschließen des Ölfilters 10 weist der Filter 12 einen Verschlussdeckel 26 auf. Der Verschlussdeckel 26 ist fest mit dem Filtermaterial 22 verbunden. Der Verschlussdeckel 26 ist dazu vorgesehen, an dem Verschluss 21 des Filtergehäuses 1 1 angebracht zu werden, um den ölfilter 10 zu schließen. Dazu weist der Verschlussdeckel 26 beispielsweise ein Formschlusselement auf, das mit dem Verschluss 21 des Filtergehäuses 1 1 formschlüssig verbindbar ist. Zum Befüllen des ölkreislaufs mit Betriebsmittel umfasst der Verschlussdeckel 26 einen verschließbaren Einfüllstutzen. Über den Einfüllstutzen kann ein Betriebsmittel direkt in den ersten Ölraum des Ölfilters 10 eingefüllt werden. For closing the oil filter 10, the filter 12 has a closure lid 26. The closure lid 26 is firmly connected to the filter material 22. The closure cap 26 is intended to be attached to the closure 21 of the filter housing 11 to close the oil filter 10. For this purpose, the closure lid 26, for example, a positive locking element, which is positively connected to the closure 21 of the filter housing 1 1. For filling the oil circuit with operating means, the closure lid 26 comprises a closable filler neck. About the filler neck a resource can be filled directly into the first oil chamber of the oil filter 10.
