    • 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.
    • 径向型结构的压缩机或涡轮机,例如用于内燃机的排气涡轮增压。 可调引导轮在流体流动壳体的径向移动的环形空间中与径向涡轮机或压缩机转子协调,其导向叶片在每种情况下以一体式构造,其中轴承销和致动杆以与轴承成一定角度突出 针脚。 为了便于将这种导向叶片组装在流体流动壳体的壳体壁的轴承孔中,壳体壁沿轴承孔的中心分开。 结果是,轴承孔径向可以接近以插入轴承销。 通过这种外壳和导向轮的结构,组装费用远远小于叶片的多部分结构。 同时,流动机械的运行可靠性随着可拆卸连接的增加而增加。
