    • A radial flow turbine including a rotor having a plurality of vanes defining an inlet, an outlet, and a flow path therebetween. A shroud is positioned to cover at least a portion of the flow path and a housing is positioned to at least partially support the rotor for rotation about a rotational axis. The housing at least partially defines a chamber for the receipt of a flow of products of combustion. A plurality of nozzle guide vane assemblies are positioned to provide fluid communication between the chamber and the inlet. Each of the plurality of nozzle guide vane assemblies is positioned adjacent another nozzle guide vane assembly to at least partially define one of a plurality of converging flow paths. Each nozzle guide vane assembly includes a guide vane positioned between the shroud and the housing and including an aperture therethrough. A bolt engages with the shroud and extends through the aperture to sandwich the guide vane between the shroud and the housing. A resilient member having a stiffness less than the bolt cooperates with the bolt to apply a compressive force to the guide vane.
    • 一种径向流动涡轮机,包括具有多个叶片的转子,所述多个叶片限定入口,出口和在其间的流动路径。 护罩被定位成覆盖流路的至少一部分,并且壳体被定位成至少部分地支撑转子以围绕旋转轴线旋转。 壳体至少部分地限定用于接收燃烧产物流的室。 定位多个喷嘴引导叶片组件以提供腔室和入口之间的流体连通。 多个喷嘴引导叶片组件中的每一个被定位成邻近另一个喷嘴导向叶片组件以至少部分地限定多个会聚流动路径中的一个。 每个喷嘴引导叶片组件包括定位在护罩和壳体之间并包括穿过其中的孔的引导叶片。 螺栓与护罩接合并延伸穿过孔,以将导叶夹在护罩和壳体之间。 具有小于螺栓的刚度的弹性构件与螺栓配合以向导向叶片施加压缩力。
