Patent number: 11346236Abstract: A guide vane for a variable turbine geometry and a turbine assembly provided with same are described. The guide vane has an outer face that is at least partly concave in design. The inner face opposite the outer face may also be at least partly concave in design. This gives the guide vane a good functional capability when arranged in a vane ring of a turbine, since an overflow through the gap between the guide vane and the neighboring walls is reduced.Type: GrantFiled: January 12, 2021Date of Patent: May 31, 2022Assignee: Vitesco Technologies GmbHInventors: Ivo Sandor, Sebastian Wittwer, Ralf Böning

Patent number: 11060453Abstract: Disclosed is a turbocharger for an internal combustion engine, having a bearing housing. A turbocharger rotor is mounted to be rotatable in the bearing housing about the rotor axis of rotation of its rotor shaft, wherein a turbine wheel is arranged for conjoint rotation on the rotor shaft and in a turbine housing fixed on the bearing housing. Between the rotor shaft and the bearing housing, an oil seal for sealing the bearing housing with respect to the turbine housing is arranged between the turbine wheel and a radial bearing associated with the turbine wheel in order to seal the bearing housing with respect to the turbine housing. A predetermined breaking point is formed for the turbocharger rotor of the turbocharger which lies in a breaking point region and extends axially between the turbine wheel back and an axial end, facing the turbine wheel back, of the rotor-shaft oil seal.Type: GrantFiled: October 25, 2019Date of Patent: July 13, 2021Assignee: Vitesco Technologies GmbHInventors: Ralf Böning, Michael Klaus, Dirk Frankenstein, Bernhard Lehmayr, Bruno Ferling

Patent number: 10774732Abstract: An exhaust-gas turbocharger for an internal combustion engine includes an intake duct for air, an exhaust-gas duct, a turbine arranged in the exhaust-gas duct, and a compressor impeller arranged in the intake duct, which turbine and compressor impeller are both arranged on a common shaft, wherein the exhaust-gas duct has a spiral housing which coaxially surrounds the turbine, and wherein, between the spiral housing and the turbine, a ring-shaped gap is provided through which the exhaust-gas flow flows circumferentially to the turbine, and wherein, in the ring-shaped gap, guide vanes are arranged which are rotatable about an adjustment axis by an adjustment mechanism for controlling the flow resistance. To compensate thermal expansions and shrinkages of the guide vanes under different operating conditions, the adjustment mechanism additionally has a displacement mechanism for displacing the guide vanes in the ring-shaped gap. The displacement mechanism is directly coupled to the adjustment mechanism.Type: GrantFiled: December 29, 2017Date of Patent: September 15, 2020Assignee: VITESCO TECHNOLOGIES GMBHInventors: Jan Ehrhard, Ralf Böning
