Patent number: 9192885Abstract: The intake air filter according to the invention is for cleaning intake air for internal combustion engines, in particular in vehicles. To this end, the intake air filter comprises an openable housing (10) with an inlet (14) and an outlet (15). Disposed between the inlet (14) and the outlet (15) is an annular, closed main filter element (17) and an annular, closed secondary element (31). The secondary element (31) is connected to the outlet (15), whereby no contamination can pass through to the outlet (15) when the main filter element (17) is replaced. A centering device (29, 30, 40, 41, 42) is provided on the end face opposite the outlet (15) between the secondary element (31) and the main filter element (17), said centering device being used to fix the position of the secondary element (31) within the main filter element (17). This prevents relative movements between the main filter element (17) and the secondary element (31).Type: GrantFiled: June 19, 2014Date of Patent: November 24, 2015Assignee: MANN+HUMMEL GMBHInventors: Werner Blossey, Mario Rieger, Joachim Schuldt

Patent number: 8741016Abstract: A filter device has a compact filter made of a filter material that is wound spirally. A star filter that is made of a filter material that has folds arranged in a star shape surrounds the compact filter. The filter device has a cylindrical shape. A fluid to be filtered passes the compact filter in an axial direction and the star filter in a radial direction. The filter device is exchangeable and is mounted in a filter housing such that the compact filter and the star filter have a common raw side and a common clean side that are separated from each other.Type: GrantFiled: January 31, 2012Date of Patent: June 3, 2014Assignee: Mann + Hummel GmbHInventors: Yassine Maaradji, Jens Hähn, Jan Zink, Joachim Stinzendörfer, Stefan Becker, Karlheinz Münkel, Michael Wolf, Werner Blossey, Mario Rieger, Ralf Poh, Josef Rohrmeier, Thomas Sieber, Andreas Pelz, Rolf Sanders, Manfred Winter
