Publication number: 20200108337Abstract: A filter arrangement for liquids has a filter housing and a functional carrier arranged inside the filter housing. A cylindrical filter element is inserted axially into the filter housing and defines an unfiltered side and a filtered side inside the filter housing. A non-return diaphragm is arranged on the filter element within the filter housing, wherein the non-return diaphragm is connected to the functional carrier and held at an axial spacing against a stop of filter housing so as to effect an axial and/or radial sealing action of the unfiltered side relative to the filtered side of the filter arrangement.Type: ApplicationFiled: October 8, 2019Publication date: April 9, 2020Inventors: Markus Kolczyk, Rainer Loos, Daniel Lucas, Sven Epli, Herbert Jainek, Ralf Blum, Joerg Kramer

Patent number: 8920649Abstract: An oil filter for an internal combustion engine has a filter housing having an interior and an exchangeable filter cartridge arranged in the interior of the filter housing. A drainage valve is arranged in the filter housing and has a valve seat and a valve member. The valve member is movable relative to the valve seat in an opening direction that is parallel and coaxial to a longitudinal axis of the filter housing and oriented toward the interior of the filter housing. The valve member is received in the valve seat in a closing direction opposite to the opening direction. The valve member can be pushed out of the filter housing in the closing direction. The valve member and the filter cartridge form together a servicing unit for joint exchange of the valve member and the filter cartridge.Type: GrantFiled: December 16, 2008Date of Patent: December 30, 2014Assignee: Mann+Hummel GmbHInventor: Rainer Loos

Publication number: 20090127170Abstract: A filter device for filtering liquids in internal combustion engines has a filter housing and a filter element inserted into the filter housing. A liquid to be filtered is introduced into the filter housing and flows through the filter element. An overflow valve is arranged between an entry side and a clean side of the filter element and has a valve body. The overflow valve is in an open position when a pressure of the liquid at the entry side of the filter element exceeds a threshold value. The valve body of the overflow valve is a sealing hose placed between the entry side and the clean side onto a cylindrical supporting body arranged in the filter housing. Flow openings are provided in the cylindrical supporting body. The sealing hose is arranged at the clean side of the supporting body.Type: ApplicationFiled: May 12, 2006Publication date: May 21, 2009Applicant: MANN+HUMMEL GmbHInventors: Markus Kolczyk, Dieter Amesoder, Sven Epli, Sascha Bauer, Michael Thienel, Rainer Loos

Publication number: 20080308487Abstract: A filtering device for filtering liquids features a pot-shaped filter housing for receiving a filter element contained therein, the filter housing being removably engaged with a connecting component (such a cover or a flange) by means of a bayonet connection. The bayonet connection includes a first positive-engaged element at the filter housing and a second positive-engaged element secured to the connecting component. The positive-engaged elements are to be brought into an axially positive locking position by axially shifting and rotating them around the housing's longitudinal axis. Furthermore, a blocking stage with a projection extending in axial direction is realized in one positive-engaged element; the allocated positive-engaged element abuts the projection in locking position, which allows also a positive locking position in circumferential direction.Type: ApplicationFiled: June 4, 2008Publication date: December 18, 2008Applicant: MANN+HUMMEL GMBHInventors: Michael Thienel, Rainer Loos
