Patent number: 9657652Abstract: A valve assembly has a housing with a first inlet, a second inlet, a first outlet, and a second outlet. A first flow path is between the first inlet and the first outlet, a second flow path is between the second inlet and the first outlet, and a third flow path is between the first inlet and the second outlet. A closure element is movably supported in the housing and in a by-pass position opens the first flow path and closes at least the second flow path, and in a normal position closes the first flow path and opens the second flow path and the third flow path. A flow guiding element is on the closure element, and which in the normal position protrudes into the second flow path and is coupled to the closure element to urge, in a gas flow from the second inlet to the first outlet, the closure element into the normal position. An exhaust gas system includes the valve assembly and an exhaust gas heat exchanger.Type: GrantFiled: August 4, 2014Date of Patent: May 23, 2017Assignee: Faurecia Emissions Control Technologies, Germany GmbHInventors: Hans-Christoph Hossfeld, Arthur Wurzer

Patent number: 9624800Abstract: A vaporizer for an exhaust system of an internal combustion engine has a vaporizer tube and a holding sleeve in which the vaporizer tube is inserted. A clamping sleeve sits on the vaporizer tube. The vaporizer tube includes two circumferentially surrounding clamping surfaces which protrude in a radial direction and cooperate with the holding sleeve and the clamping sleeve such that the clamping surfaces are clamped between the holding sleeve and the clamping sleeve by an axial clamping force to be gastight. At least one of the holding sleeve and the clamping sleeve includes a surrounding sealing edge which rests against the respective clamping surface via a line contact and forms an annular sealing seat. The vaporizer further includes a device preventing relative rotation between the holding sleeve and the vaporizer tube.

Patent number: 8997352Abstract: A method for manufacturing exhaust gas ducting devices provides each device with an outer housing having an insert clamped therein, wherein the insert comprises a substrate traversed by exhaust gas, and an elastic compensating element surrounding the substrate. The method includes spreading each individual compensating element on a base and deforming the compensating element substantially vertical to the base by exerting a pressure such that the entire compensating element is subjected to a full-surface load. Then a setpoint deformation of the compensating element is determined, which is necessary to achieve a specified setpoint pressure. The method further includes determining at least one parameter of the substrate individually, placing the compensating element around the substrate, and mounting the insert thus obtained in an outer housing having inside dimensions that correspond to outside dimensions of the insert with the determined setpoint deformation.Type: GrantFiled: June 30, 2010Date of Patent: April 7, 2015Assignee: Faurecia Emissions Control Technologies, Germany GmbHInventors: Uwe Troeger, Manfred Stiglmair
