  • Variable capacity turbocharger
    Patent number: 12025012
    Abstract: A variable capacity turbocharger includes a turbine impeller, a gas inlet passage fluidly coupled to the turbine impeller, a nozzle vane located in the gas inlet passage, a drive assembly that rotates the nozzle vane, a drive chamber accommodating the drive assembly and including a region configured to store liquid in the drive chamber, and a liquid passage fluidly coupled with the drive chamber and configured to discharge the liquid from the drive chamber. A surface of the liquid passage has a greater surface roughness than the region of the drive chamber.

  • TURBINE WITH BIASED NOZZLE VANE MEMBERS
    Publication number: 20240084715
    Abstract: A turbine includes a turbine wheel, a housing having a flow path for a gas, a variable geometry device to guide the gas from the flow path to the turbine wheel, and a biasing member. The variable geometry device includes one or more nozzle vane member, each having a nozzle vane, a nozzle shaft and a nozzle link plate. The biasing member is in contact with the nozzle link plate of the nozzle vane member, to urge the nozzle vane member against a contact surface of the turbine.
