Abstract: An oil filter assembly (10) has a receiving chamber (18) that can be closed by a cover element (14) and a spring-loaded supporting tube (22) that is fixed in the receiving chamber and is designed to receive a filter element (20) that can be radially traversed by oil. The supporting tube (22) is axially displaceable between an operating position and a drain position in such a way that, in the operating position when the receiving chamber is closed by the cover element (14), the tube closes a drain opening (42). When the receiving chamber is open in the drain position, the tube releases the drain opening. The supporting tube is mounted to rotate through a rotational angle that is limited by two rotational stops (41, 43) in the housing and the cover element has follower sections (66, 68, 70) that co-operate with the supporting tube and/or filter element to rotate the supporting tube through the rotational angle when the cover element is screwed on and/or unscrewed.

Abstract: An oil filter assembly (10) has a receiving chamber that can be closed by a cover element and a spring-loaded supporting tube (22) that is fixed in the receiving chamber (18) and is designed to receive a filter element (20) that can be radially traversed by oil, the supporting tube being axially displaceable between an operating position and a drain position in such a way that, in the operating position when the receiving chamber is closed by the cover element (14), the tube closes a drain opening (42) and when the receiving chamber is open in the drain position, the tube releases a drain opening (42). The cover element (14) has a supporting tube contact area (58) on the side facing the receiving chamber in such a way that during the closing of the receiving chamber (14) when the filter element is located on the supporting tube (22), pressure is exerted on the tube by the support tube contact area (58), thus displacing the tube into the operating position.

A guide (62) for a compensating body of the outlet valve is provided on a part that is separate from the housing (12). The compensating body (58) serves to compensate for axial tolerances of the housing and/or of the filter element.

Abstract: The invention relates to an oil filter arrangement having a housing comprising a receiving space for a filter element, wherein a discharge opening is provided at the bottom of the receiving space and a discharge valve is provided in the discharge opening wherein the discharge valve comprises a valve body, which is movable between a closing position and an opening position in a displaceable manner and is moved to the locking position by a first spring element when the filter element is inserted, wherein the first spring element is disposed on the valve body on the side of the valve body facing away from the discharge opening and is configured as a compound spring having a flat, bent metal band. The metal band acts against the filter element or against an end disk of the filter element when the filter element is inserted.

Abstract: A vane machine comprises an inner rotor (28) and an outer rotor (51). A plurality of radially extending vane elements (32) separates first vane chambers (89) from one another. The van elements (32), with a radially inner end region (34), are accommodated in the inner rotor (28) in a radially displaceable manner and, with a radially outer end region (36), are accommodated in the outer rotor (51) in a pivotable manner. It is proposed that the radially inner end regions (34) of the vane elements (32) be accommodated in the inner rotor (28) at a fixed angle and that the outer rotor (51) comprise individual shoes (38) which are separate for each vane element (32) and in which the vane elements (32) are accommodated in a pivotable manner.
