Zwischen dem aufschraub baren Gehäusedeckel 5 und dem Filtergehäuse 2 ist ei ne Dichtung 6 vorgesehen. Ein Filterelement 7 aus Pa pier ist als Sternfilter ausgebildet und taschenver klebt und trennt den Roh- 8 vom Reinraum 9. An seinen Enden ist es jeweils auf seinem Innenumfang mit einer Hülse 10 aus verfestigtem Papier versehen. Zur Ver steifung des Filterelements 7 ist außerdem noch eine Hülse 11 im Mittelbereich des Filterelementes 7 vor gesehen. Durch die Herstellung eines derartigen Fil terelements aus einem einheitlichen Werkstoff ist ge währleistet, daß dieser beim Filterwechsel auf um weltfreundliche Weise entsorgt werden kann.A liquid filter 1 shown in FIG. 1 consists of egg nem cup-shaped filter housing, which, at one end with inlet 3 and outlet openings 4 , can be connected, for example, to a mounting head and is closed at its other end by a removable housing cover 5 . Between the screw-on housing cover 5 and the filter housing 2 , a seal 6 is provided. A filter element 7 made of paper is designed as a star filter and taschenver glues and separates the raw 8 from the clean room 9 . At its ends, it is provided on its inner circumference with a sleeve 10 made of solidified paper. To stiffen the filter element 7 , a sleeve 11 is also seen in the central region of the filter element 7 . The manufacture of such a Fil terelements from a uniform material ensures that this can be disposed of in a world-friendly manner when changing the filter.
Das Filterelement 7 wird im Filtergehäuse durch ein hülsenförmiges Trägerteil 12 aus Kunststoff fixiert, wobei die fest mit dem Filterelement 7 verbundenen Hülsen 10 an Dichtungen 13, 14 anliegen. Die Dichtung 13 ist U-förmig ausgebildet und umgreift das untere Ende des Trägerteils 12, so daß gleichzeitig eine Ab dichtung zwischen Roh- 8 und Reinraum 9 und dem Inne ren 15 des Trägerteils erreicht wird. Die ringförmige Dichtung 14 ist im oberen Bereich des Trägerteils 12 in einer entsprechenden Nut 16 gelagert. Das Träger teil 12 besteht aus zwei Einzelteilen 12a, b, die über ein Gewinde miteinander verschraubt sind. In ei ner Zwischenwand 17 des unteren Einzelteils 12b des Trägerteils 12 ist ein Rücklaufsperrventil 18 vorge sehen, so daß einerseits erst ab einem vorbestimmten Druck das gereinigte Schmieröl über die Ablauföffnung 4 abfließen kann und andererseits ein Leerlaufen des Filters bei Stillstand des Verbrennungsmotors vermie den wird. In einer Zwischenwand 19 des oberen Einzel teils 12a des Trägerteils 12 ist ein Überströmventil 20 vorgesehen, das bei einer entsprechenden Druckdif ferenz eine Verbindung zwischen dem Inneren 15 des Trägerteils 12 und dem Rohraum 8 herstellt. Das obere Einzelteil 12a des Trägerteils weist Öffnungen 21 auf, die eine Verbindung zwischen dem Reinraum 9 und dem Inneren 15 des Trägerteils 12 herstellen.
