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
