Abstract

A turbine impeller supplies a high-pressure fluid through a scroll flow route and / or a exhaust supply port of a fixed nozzle and includes: blade components converting the fluid into a rotational force; and a rotor, configured with the blade components and can rotate around a specified rotational axis, wherein a direction, relative to a gas relative inflow velocity of the rotor, specified by using the fluid supply port as a starting point and subtracting a rotational velocity component of the rotor from a supply velocity component of the fluid is set to not intersect with the rotational axis of the rotor; and a shape, from a halfway portion to a front edge portion, of the blade component inclines, relative to a direction from a center of the rotor to an upstream portion of the blade component, toward front side of a rotating direction of the rotor by a specified angle.

Description

technical field [0001] The present invention relates to a turbine impeller. Background technique [0002] Conventionally, as a turbine impeller installed in a flow path of an internal combustion engine (hereinafter referred to as an engine), there is known a turbine impeller in which the shape of the tip of the blade of the turbine impeller is oriented toward the gas relative inflow velocity of the following velocity triangle: The inflow direction of V is formed so that the velocity triangle is formed by the inflow velocity C of the exhaust gas flowing into the rotor blade inlet, the rotational velocity U in the circumferential direction of the rotor blade, and the relative gas inflow velocity V (for example, refer to Patent Document 1). . [0003] [Prior art literature] [0004] [Patent Document] [0005] [Patent Document 1] Japanese Patent Laid-Open No. 2011-132810 Contents of the invention [0006] [Problem to be solved by the invention] [0007] However, the shape...
