Patent number: 11156151Abstract: A regulating device for an exhaust turbocharger, is received in an exhaust gas conducting section of the exhaust turbocharger, with the aid of the regulating device a fluid flow onto a turbine wheel rotatably received in the exhaust gas conducting section can be conditioned, a through-flow opening formed in the exhaust gas conducting section is to be opened and closed with the aid of a valve element of the regulating device, the valve element is arranged on a pivot arm of the regulating device, and wherein the valve element has a sealing surface for avoiding a leak in a closed position of the regulating device. To reduce secondary torques acting upon the valve element during operation, a connection is formed between the pivot arm and the valve element in or at least close to a center of gravity of an effective valve element body of the valve element.Type: GrantFiled: January 8, 2020Date of Patent: October 26, 2021Assignee: IHI CHARGING SYSTEMS INTERNATIONAL GMBHInventors: Zdenek Reif, Manfred Guthoerle, Rohit Pawar, Ralf Schawer
