A vane for a vane cell vacuum pump. The vane can be rotated about an axis of rotation by a rotor in a pump chamber and guided in the longitudinal direction in the rotor, with an upper side and a lower side to abut against the bottom and the ceiling of the pump chamber, with a rear side opposite a front side to limit the pressure chambers, with at least one face to slidably abut against an inside wall of the pump chamber on the casing side. The vane comprises a base body of a first plastic material and a vane end molded of a second plastic material to the base body forming the face. The base body comprises a mounting section around which the vane end is formed. The mounting section comprises at least one recess transverse to the front side and/or the rear side.

An oil filter assembly () has a receiving chamber () that can be closed by a cover element () and a spring-loaded supporting tube () that is fixed in the receiving chamber and is designed to receive a filter element () that can be radially traversed by oil. The supporting tube () 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 (), the tube closes a drain opening (). 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 () in the housing and the cover element has follower sections () 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.

Oil filter assembly and associated filter element

An oil filter assembly () has a receiving chamber that can be closed by a cover element and a spring-loaded supporting tube () that is fixed in the receiving chamber () and is designed to receive a filter element () 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 (), the tube closes a drain opening () and when the receiving chamber is open in the drain position, the tube releases a drain opening (). The cover element () has a supporting tube contact area () on the side facing the receiving chamber in such a way that during the closing of the receiving chamber () when the filter element is located on the supporting tube (), pressure is exerted on the tube by the support tube contact area (), thus displacing the tube into the operating position.

Oil filter assembly

An oil filter arrangement, has a housing () with a receiving space () for a filter element () which can be inserted into the housing and through which oil can flow radially, with an oil inlet () and an oil outlet (), and with a supporting tube () which is present in the receiving space and supports the filter element. The supporting tube is inserted into the receiving space and is fastened to the housing in such a manner that it remains in the housing when the filter element is exchanged.

Oil filter

An oil filter arrangement comprises a housing, which has a receiving chamber for a filter element which can be cross-flowed in a radial manner by oil and which can be inserted into the housing, a support tube which supports the filter element when it is inserted, a housing cover which closes the receiving chamber, and a drainage channel which is provided in the base area of the receiving chamber. The support tube is fixed to the housing and it remains therein when the filter element is replaced and that a drainage plate, which comprises closing means for closing the drainage channel and which is arranged in an axially displaceable manner, to a limited extent, on the support tube, is arranged in the base area of the receiving chamber.

Oil filter arrangement

An oil filter assembly () comprises a housing () that has a holding space for a filter element (), which can be placed inside the housing and through which oil can radially flow, an oil inlet, an oil outlet, and a supporting tube (), which supports the filter element. A guide () for a compensating body of the outlet valve is provided on a part that is separate from the housing (). The compensating body () serves to compensate for axial tolerances of the housing and/or of the filter element.

Hydraulically or pneumatically controlled seat valve (), in particular a pressure control valve, having a valve seat () formed in a base part () which cooperates with the sealing surface of a valve body () displaceably disposed in a cover part (), wherein the base part () and the cover part () are connected to each other, the base part () having an at least sectionally circumferential collar () which faces radially outwardly for mounting the seat valve () to a further component (), in particular to a housing, using a welded joint.
