VARIABLE DISPLACEMENT-TYPE SUPERCHARGER
Document Type and Number:
WIPO Patent Application WO/2021/192414
Kind Code:
A1
Abstract:
This variable displacement-type supercharger comprises: a nozzle flow path which allows gas heading toward a turbine wheel from a scroll flow path to pass; a shroud-side ring and a hub-side ring which face each other in the rotational axis line direction of the turbine wheel and form the nozzle flow path therebetween; a bearing hole provided to the shroud-side ring; a bearing hole provided to the hub-side ring; and a nozzle vane disposed in the nozzle flow path and supported on both sides by the bearing holes, wherein, at room temperature, the center axial line of the bearing hole is positioned inward in the radial direction as compared to the center axial line of the bearing hole, and when a predetermined temperature difference has occurred between the shroud-side ring and the hub-side ring during operation, the center axial line is positioned outward in the radial direction as compared to the center axial line.
