Eine weitere Ausgestaltung der Erfindung sieht vor, die Ventilendscheibe als Endscheibe des Filterelementes zu gestalten. Es besteht auch die Möglichkeit, in einem Zwei- Komponenten-Herstellverfahren beide Elemente in einem Arbeitsgang zu produzieren und diese mit dem zick-zack-förmig gefalteten Filtermaterial zu verbinden. Das Filterele­ ment weist Radialdichtungsflächen auf, diese liegen an dem Mittelrohr des Filters an und bilden über den Kontakt mit dem Mittelrohr eine Dichtung zwischen Rohflüssigkeitsseite und Reinflüssigkeitsseite.Another embodiment of the invention provides that the valve end plate as an end plate to design the filter element. There is also the option of Component manufacturing process to produce both elements in one operation and to connect them with the zigzag folded filter material. The Filterele element has radial sealing surfaces, these are in contact with the center tube of the filter form a seal between the raw liquid side through contact with the center tube and pure liquid side.

Weiterbildungsgemäß kann ein Überdruckventil in dem Filter vorgesehen sein. Dies hat die Aufgabe, bei einem erhöhten Differenzdruck zwischen Rohölseite und Reinölseite einen Bypass zu öffnen.According to a further development, a pressure relief valve can be provided in the filter. this has the task at an increased differential pressure between the crude oil side and pure oil side open a bypass.

Ein Filterelement wird in einem nebengeordneten Patentanspruch beschrieben. Dieses Filterelement ist besonders kostengünstig aufgebaut und schafft in einfacher Weise ein wirksames Rücklaufsperrventil in Verbindung mit einem in dem Gehäuse angeordneten Ventilsitz oder einem Gehäuseabsatz.A filter element is described in an independent claim.
