Title:
SUPERCHARGER
Document Type and Number:
WIPO Patent Application WO/2024/075370
Kind Code:
A1
Abstract:
This supercharger comprises: turbine blades; a turbine housing including a flow path through which there flows a gas received from a flow inlet; a variable-capacity mechanism disposed in the turbine housing, the variable-capacity mechanism receiving the gas from the flow path and guiding the received gas to the turbine blades; and a disc spring that applies, to the variable-capacity mechanism, a biasing force for pressing the variable-capacity mechanism toward the turbine housing. The turbine housing has a turbine housing flange reverse surface that contacts the variable-capacity mechanism along the rotation-axis direction of the turbine blades. The variable-capacity mechanism has a nozzle-ring-outer-side flange main surface that contacts the turbine housing flange reverse surface along the rotation-axis direction. The turbine housing flange reverse surface and/or the nozzle-ring-outer-side flange main surface is machined to improve the coefficient of friction thereof.
