Patent number: 8114278Abstract: The invention concerns a fuel filter 10, in particular for diesel fuels, that comprises a housing 11 and a filter medium 12. The filter medium 12 is arranged by means of a filter medium holder 24 in the housing, wherein the filter medium holder comprises a venting bore 25. Through the venting bore 25 gases that collect in the upper area of the fuel filter can pass from the crude chamber 21 into the clean chamber 22. For avoiding that contaminants can escape through a clean outlet 18 from the fuel filter 10 and damage components downstream, a clean medium 26 is provided that retains such contaminants.Type: GrantFiled: January 11, 2008Date of Patent: February 14, 2012Assignee: Mann & Hummel GmbHInventors: Sonia Lorente, Michael Wolf, Günter Jokschas, Horst Croissant

Publication number: 20100224549Abstract: A filter device for a motor vehicle has a filter element with a porous ceramic support body provided with one or more passages for receiving a liquid to be filtered and filter membranes formed on inner walls of the passages. The liquid to be filtered passes through the filter membranes into the support body and exits from the support body through a circumferential surface of the support body. At least one compensation element is arranged at an end face of the support body. The compensation element is elastically deformable for providing an additional liquid volume that is generated when the liquid expands due to freezing.Type: ApplicationFiled: March 8, 2010Publication date: September 9, 2010Applicant: MANN+HUMMEL GMBHInventors: Michael Micke, Guenter Jokschas, Martin Weindorf, Dieter Schreckenberger, Elke Duerr

Patent number: 7637976Abstract: An air filter insert including at least one filter element (2; 4; 11) and a seal (3; 7) extending along outer edges of one side of the filter insert (2; 4; 11) and via which the filter insert is sealingly seated against housing sections (5, 6) of a surrounding filter housing. The filter insert (2; 4; 11) is configured such that the air can easily flow into or out of the structural space on the one side of the filter element with a minimum pressure drop. The filter insert (11) may be at least partially covered on the inflow and/or discharge side by a semi-permeable component (12), which at least partially equalizes the pressure distribution in the air stream.Type: GrantFiled: June 14, 2006Date of Patent: December 29, 2009Assignee: Mann & Hummel GmbHInventors: Timo Dirnberger, Christoph Baumann, Guenter Jokschas, Markus Roehrig
