Patent number: 8636902Abstract: 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.Type: GrantFiled: July 19, 2010Date of Patent: January 28, 2014Inventors: Peter Jungmann, Benjamin Diehl, Stefan Heinz

Patent number: 8282821Abstract: 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.Type: GrantFiled: May 19, 2007Date of Patent: October 9, 2012Assignee: Joma-Polytec Kunststofftechnik GmbHInventors: Jan Maier, Friedhelm Pfitzer, Alexander Maute, Stefan Heinz, Peter Jungmann, Matthias Knoell

Patent number: 7842183Abstract: An oil filter assembly (10) comprises a housing (12) that has a holding space for a filter element (20), which can be placed inside the housing and through which oil can radially flow, an oil inlet, an oil outlet, and a supporting tube (22), which supports the filter element. 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.Type: GrantFiled: May 10, 2006Date of Patent: November 30, 2010Assignee: Joma-Polytec Kunststofftechnik GmbHInventors: Stefan Heinz, Friedhelm Pfitzer, Peter Jungmann, Alexander Maute
