Abstract

A compressor or a turbine of the radial type of construction as is used, for example, for exhaust gas turbocharging of an internal combustion engine. Adjustable guide wheels are coordinated to a radial turbine or compressor rotor in a radially traversed annular space of the fluid flow housing, whose guide blades are constructed in each case in one piece with the bearing pins and the actuating levers projecting at an angle from the bearing pins. For facilitating assembly of such guide blades in bearing apertures of a housing wall of the fluid flow housing, the housing wall is divided along the center of the bearing bores. As a result thereof, the bearing bores are radially accessible for the insertion of the bearing pins. With this construction of housing and guide wheel, the assembly expenditure is considerably smaller than with multipartite construction of the blades. At the same time, the operating reliability of the fluid flow machine is increased with the few detachable connections.
