Patent number: 11174823Abstract: A hot gas exhaust recirculation valve includes a housing containing a duct for conducting gases, a drive chamber, and a valve stem which is mounted in the housing. The valve stem can be displaced in its longitudinal direction thereof and extends from the drive chamber into the duct. The end of the valve stem that is situated in the drive chamber is coupleable to a drive device. A closing body is fastened to the other end of the valve stem. The closing body is situated in the duct and has a closed position in which it separates an upstream section of the duct from a downstream section of the duct. A sealing ring surrounds the valve stem and is arranged between the duct and the drive chamber.

Patent number: 10077743Abstract: A hot gas valve has a housing, in which a gas duct is formed with an inlet and an outlet, and a valve device for controlling the fluid flow through the gas duct. The housing has at least one cooling duct for liquid cooling of the housing, wherein the gas duct is shielded with respect to the housing by means of a thermal shield, which consists of a material which has a greater thermal stability than the material of which the housing consists. The valve device has a closure body situated in the gas duct, which closure body is held on a valve shaft mounted in the housing by means of at least one bearing. The bearing may consists of a material having good thermal conductivity. The valve shaft is sealed by an elastomer shaft sealing ring on the side of the bearing facing away from the gas duct.Type: GrantFiled: February 12, 2015Date of Patent: September 18, 2018Assignee: BORGWARNER ESSLINGEN GMBHInventors: Bernd Bareis, Hans-Ulrich Gross, Till Neumann

Patent number: 9759122Abstract: A thermostatic valve for controlling the temperature of the coolant in an internal combustion engine controls the flow of coolant between the internal combustion engine and a heat exchanger. The valve includes an actuation element which functions in a temperature-dependent manner for actuating lift of a main valve and of a bypass valve in a valve housing. The actuation element has a stationary piston supported on a valve housing part. A housing can be displaced relative to the piston and on which the valve members of the main valve and of the bypass valve are arranged. Further provided is a monitoring device for the position of the main valve, which works in a contactless manner and which has at least one sensor element contained in the valve housing part, and at least one associated permanent magnet for generating a magnetic field to which the sensor element is exposed.Type: GrantFiled: March 16, 2015Date of Patent: September 12, 2017Assignee: BorgWarner Esslingen GmbHInventors: Ahmet Aydin, Bernd Bareis, Christof Clauss, Marc Schneider

Patent number: 9752687Abstract: An exhaust line valve for an internal combustion engine. A closure body is arranged in a duct of the valve and is fastened to a shaft. The closure body when closed separates upstream and downstream duct sections. Two projections extend into the duct, each having a valve seat pointing in an opposite direction of the duct. By pivoting the closure body from its closed position, the sealing surfaces of the closure body are raised from their respective valve seats. A polymer seal is arranged on the valve seats and in the closed position the polymer seal sealingly contacts the associated sealing surface of the closure body. A circumferential surface of the shaft or the closure body is located in an edge region of the closure body. The polymer seal contacts in a sealing manner at least a region of the circumferential surface facing the upstream section of the duct.Type: GrantFiled: August 26, 2015Date of Patent: September 5, 2017Assignee: BorgWarner Esslingen GmbHInventors: Bernd Bareis, Julian Haselmaier, Patrick Wilde

Patent number: 9739241Abstract: A valve for an exhaust gas line of an internal combustion engine in which a closure body is arranged in a duct and is positioned in a recess of a shaft, the closure body being pivotable about a rotation axis of the shaft. The closure body has two sides and a circumferential surface arranged between the two sides. The circumferential surface has sections with different external dimensions. A first external dimension of the circumferential surface of the closure body in a first section is smaller than the smallest internal dimension between end regions of the recess of the shaft in which the closure body sits. A second external dimension of the circumferential surface in a second section is greater than the smallest internal dimension of the recess of the shaft. The circumferential surface contacts the shaft in each of the two end regions of the recess.Type: GrantFiled: March 21, 2016Date of Patent: August 22, 2017Assignee: BorgWarner Esslingen GmbHInventors: Bernd Bareis, Julian Haselmaier, Patrick Wilde

Patent number: 9638140Abstract: A low pressure valve for controlling exhaust gas recirculation in an internal combustion engine for a vehicle includes a housing, which contains a channel section for exhaust gas guidance, and a valve element disposed in the housing to control the exhaust gas passage in the channel section. An actuating drive is mounted on the housing and adjusts the valve element. The actuating drive is formed of an electromagnetic rotary actuator with a drive shaft thereof. The drive shaft is routed in an extended manner out of a rotary actuator housing and is in the form of an actuating shaft. The actuating shaft extends continuously to the housing and protrudes into the housing transversely to the flow direction, engages therein at the valve element in a non-rotatable manner and can be rotationally adjusted about the axis to actuate the valve element.Type: GrantFiled: November 19, 2012Date of Patent: May 2, 2017Assignee: Gustav Wahler GmbH u.
