Patent number: 10105626Abstract: A sealing device (24) of a filter system (10) for filtering fluids, in particular of a motor vehicle, with a sealing ring (26) is described. The sealing ring (26) serves to seal a pipe (16), in particular a central pipe of a filter housing (12), that penetrates through a flange-sided opening (18) of an end plate (20), in particular of an end element of a filter element (14). The sealing ring (26) features a central section (58) that connects it with the end plate (20). The sealing ring (26) features in its axial direction on both sides of the central section (58) elastic sealing sections (60, 62) which cause each a reduction of the inner diameter of the sealing ring (26) compared with the central section (58).Type: GrantFiled: April 28, 2014Date of Patent: October 23, 2018Assignee: MANN+HUMMEL GmbHInventors: Guenter Jokschas, Marco Schweikart, Martin Weindorf

Publication number: 20160354713Abstract: A filter element (10) has at least a first filter body (12) that is separated in a fluid-tight fashion from a second filter body (14) and is arranged above the second filter body (14) in an axial direction (L). A first flow outlet (24) proceeds from the first filter body (12) and a second flow outlet (26), proceeding from the second filter body (14), is arranged outside the first flow outlet (24) in a transverse direction (Q) perpendicular to the axial direction (L). A centering element (20) that acts in the transverse direction (Q) is arranged on an end disc (16) of an end face (15) of the filter element and corresponds to a corresponding receptacle (110) of a filter housing (108).Type: ApplicationFiled: May 29, 2016Publication date: December 8, 2016Inventors: Marco Schweikart, Martin Weindorf, Tiago Felipe Oliveira da Silva

Publication number: 20140378289Abstract: An oil cleaning device of an engine oil circuit has a centrifuge that removes particles from oil. The centrifuge has a centrifuge housing with an inlet for the oil to be cleaned and a drain for the cleaned oil. The centrifuge housing has a housing cup and a housing cover detachably connected to the housing cup. A rotor is rotatably arranged inside the centrifuge housing. The housing cover, in a mounted state of the centrifuge, closes off a bottom end of the housing cup. The drain extends through a circumferential wall of the housing cup and has a drain opening provided in a radial inner circumferential side of the circumferential wall. The drain opening has a lower boundary at the radial inner circumferential side. The housing cover has a topside with a radial outer rim arranged at the level of or above the lower boundary of the drain opening.Type: ApplicationFiled: September 12, 2014Publication date: December 25, 2014Inventors: Marco Schweikart, Martin Weindorf

Patent number: 8245698Abstract: A valve for controlling volume flows of fuel supply systems of internal combustion engines has a conduit having an inlet and an outlet defining a flow direction. A bypass opening is provided in the conduit. A sleeve is slidably arranged in the conduit and covers in one position the bypass opening completely. The sleeve has an axial through bore that connects the inlet and the outlet. An elastic element that is arranged in the conduit and exerts onto the sleeve a force that is directed toward the inlet. A counterforce is generated by the flow resistance of the sleeve that counteracts the force of the elastic element.Type: GrantFiled: January 18, 2010Date of Patent: August 21, 2012Assignee: Mann + Hummel GmbHInventors: Marco Schweikart, Bernd Nageldinger
