Abstract
A turbocharger (10) comprising: a rotating shaft (14); a turbine wheel (12); a turbine housing (31); a scroll flowpath (34) having gas flowing therethrough that rotates and drives the turbine wheel (12); a nozzle flowpath (35) that guides gas radially inwards from the scroll flowpath (34) and supplies gas to the turbine wheel (12); and a vane (53) that adjusts the amount of gas introduced in the nozzle flowpath (35). The vane (53) comprises a guide section (60) that guides the gas flow (F) in the turbine wheel (12) radially inwards.
Claims3
A turbocharger comprising:
- a rotating shaft extending along an axis;
- a turbine wheel disposed on a first end portion side of the rotating shaft, a plurality of blades being formed at intervals in a circumferential direction on the turbine wheel;
- a turbine housing accommodating the turbine wheel;
- a scroll flow path formed in the turbine housing, continuing in the circumferential direction on a radially outer side of the turbine wheel, and having gas flowing therethrough that rotates and drives the turbine wheel;
- a nozzle flow path that guides the gas radially inwards from the scroll flow path and supplies the gas to the turbine wheel;
- and
- a vane that adjusts the amount of the gas introduced in the nozzle flow path,
- wherein the vane includes a guide section that guides the gas such that at least part of the flow of the gas flows radially inwards on a trailing edge side of the blade of the turbine wheel.
