Patent number: 11118500Abstract: The invention relates to a turbine comprising a turbine housing defining a volute having a substantially annular outlet opening, a turbine wheel, and an adjusting ring, rotatable about the turbine axis, which is arranged in the turbine housing radially between the volute and the turbine wheel, wherein the adjusting ring comprises a flow channel between a radially outer first peripheral opening and a radially inner second peripheral opening, and wherein the outlet opening is fluidically coupled to the turbine wheel by the flow channel. The outlet opening and the first peripheral opening have a path, variable in the axial direction, so that during a rotation of the adjusting ring, the outlet opening and the first peripheral opening are adjusted relative to each other in such a way that an overflow cross section between the outlet opening and the first peripheral opening is variably changeable.Type: GrantFiled: March 27, 2019Date of Patent: September 14, 2021Assignee: BorgWarner Inc.Inventors: Sascha Karstadt, Mathias Kosch, Gerd Spinner, Stefan Decker, Ahmet Coksen, Jamison Taylor, Laszlo Medvegy, Stefan Muenz
