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

Patent number: 8480892Abstract: The invention concerns a filter insert (1) that is provided as an exchangeable insert in an oil filter of an internal combustion engine, as well as a corresponding oil filter. The oil filter comprises a filter housing (3) separable along a separating plane (2) and the exchangeable filter insert (1). Two housing parts (4, 5) of the filter housing (3) are sealed relative one another along the separating plane (2) by means of a seal (6). The seal (6) is captively secured on the filter insert (1).Type: GrantFiled: December 4, 2007Date of Patent: July 9, 2013Assignee: Mann + Hummel GmbHInventors: Herbert Jainek, Johannes Lampert, André Rösgen, Eric Gillenberg, Jens Hähn, Jens Gutekunst, Marco Schilling, Dietmar Klein

Patent number: 7258727Abstract: A separating apparatus which enables particles to be separated from a flowing medium by a preliminary separator which avoids the undesirably high pressure losses due to the flow resistance of known preliminary separators. The separating apparatus has a housing with an inlet and an outlet, in which a flow of air at the inlet end is caused to rotate by an inlet guide device, and is redirected again at the outlet end by an outlet guide device into a linear flow. The pressure recovery is achieved by a defined curvature and arrangement of the guide elements. The guide element curvature has an inlet contour, a retarding contour and a stabilizing contour. Preliminary separators of this type are used primarily in the air intake tracts of internal combustion engines exposed to heavy contamination, such as engines in farm machinery or construction machinery.Type: GrantFiled: August 27, 2004Date of Patent: August 21, 2007Assignee: Mann & Hummel GmbHInventors: Volker Greif, Jens Haehn

Patent number: 7004986Abstract: A filter has a filter housing and a receptacle chamber in the filter housing into which a filter element is insertable. The filter housing has a housing cover for opening and closing an opening of the receptacle chamber. The housing cover is situated in an area of the filter housing between the oncoming flow side and the outgoing flow side of the filter element.Type: GrantFiled: May 23, 2003Date of Patent: February 28, 2006Assignee: Mann & Hummel GmbHInventors: Edvard Kopec, Manfred Winter, Volker Greif, Klemens Dworatzek, Marion Hartmann, Karlheinz Muenkel, Jens Haehn, Joachim Stinzendoerfer

Patent number: 6884273Abstract: A multicell cyclone with a plurality of cyclone cells and a method for the production thereof, in which the cyclone cells of the multicell cyclone are combined into groups from which deposited particles are cleaned out by vacuum suction through channel structures. This permits better control of the discharge of separated particles. Vacuum suction of the separated particles can be effected, for instance, via openings (19) which are jointly provided for the group (21) of cyclone cells. The group of cyclone cells can furthermore be produced as a module, which can, for instance, be assembled from two parts (12, 13) in which like structural elements of a group of cyclones are combined into one respective part. This makes it possible to optimize the separation result with little structural complexity and at low production cost.Type: GrantFiled: August 28, 2002Date of Patent: April 26, 2005Assignee: Filterwerk Mann & Hummel GmbHInventors: Edvard Kopec, Volker Greif, Klemens Dworatzek, Jens Haehn, Marion Hartmann
