Patent number: 10774934Abstract: The invention relates to a bearing system 1 of a flap valve 6 consisting of a valve shaft 1.1 with a valve shaft pivot 1.2, and consisting of a separate bearing body 2 which is fastened on the end side to the valve shaft 1.1, and of a valve housing wall 3 which has a shaft bearing 3.1 in the form of a depression, the bearing body 2 being guided rotatably in the depression 3.1. Here, the bearing body 2 has a recess 2.1, into which a separate bearing piece 4 is inserted, the valve shaft 1.1 bearing indirectly via the bearing body 2 and the bearing piece 4 against the housing-side shaft bearing 3.1, the bearing body 2 and the bearing piece 4 being formed from different metals or different materials.Type: GrantFiled: November 17, 2017Date of Patent: September 15, 2020Assignee: Tenneco GmbHInventors: Marek Rybarz, Rico Weinert

Patent number: 10041419Abstract: A valve flap device having at least one valve housing having a shaft comprising a bearing surface and a valve axis, the shaft being rotationally supported about the valve axis by means of the bearing surface in the valve housing. A bearing element having a sliding bearing surface, wherein the bearing surface of the shaft contacts the sliding bearing surface. A bearing housing provided on the valve housing, in which the bearing element is supported at least in the radial direction to the valve axis, wherein the bearing element has an outer surface contacting the bearing housing. The support of the shaft is intended to be sufficiently tightly sealed, even for gaseous media, while simultaneously ensuring precise and statically determinate support.Type: GrantFiled: November 10, 2010Date of Patent: August 7, 2018Assignee: TENNECO GMBHInventors: Thomas Weidner, Rico Weinert, Alexander Schinko, Marcel Womann, Karlheinz Reichling

Patent number: 9163565Abstract: A valve flap device for an exhaust system of a motor vehicle, having at least one tubular valve housing with a flow cross section running perpendicular to a central axis and being formed by the inner geometry and a shaft which can turn about a valve axis with a valve flap mounted on the shaft, being mounted in the valve housing to close the flow cross section. The valve flap device can be made with low material input and at the same time with low fabrication expense at low costs. For this, the valve housing is made from a tubular blank of sheet metal with a tube diameter that is calibrated to the flow cross section at least partially by mechanical, plastic forming.Type: GrantFiled: May 18, 2011Date of Patent: October 20, 2015Assignee: TENNECO GMBHInventors: Marcel Womann, Marc Sommerfeld, Rico Weinert, Alexander Schinko, Christoph Schneider
