    • Disclosed is a turbine comprising a turbine wheel, a turbine scroll passage defined in a turbine casing around the turbine wheel for introduction of gas to the turbine wheel, and an axial central passage defined in the turbine casing for ejection of gas from the turbine wheel, wherein: a plurality of variable nozzles are arranged outside of a throat section having a locally minimum cross section which is defined in the turbine casing around the turbine wheel. The variable nozzles may be defined by fixed vanes and moveable vanes which cooperate with each other in such a manner that each of the moveable vanes and the corresponding fixed vane define a substantially smooth and continuous airfoil. The moveable vanes may be pivotally supported by a back plate of the casing while the fixed vanes may be integrally provided with a fixed vane member having a disk portion which defines a surface opposing the inner surface of the back plate. The moveable vanes may rotate along and between these mutually opposing surfaces for varying the cross section of the nozzles defined between the fixed vanes and the moveable vanes.
    • 公开了一种涡轮机,其包括涡轮机叶轮,涡轮机涡旋通道,其限定在涡轮机壳体周围,用于将涡轮引入涡轮机叶轮,以及限定在涡轮机壳体中用于从涡轮机叶轮喷出气体的轴向中心通道, 其中:多个可变喷嘴布置在具有限定在涡轮机壳体周围的涡轮机叶轮的局部最小横截面的喉部的外侧。 可变喷嘴可以由固定叶片和可移动叶片限定,其彼此协作,使得每个可移动叶片和相应的固定叶片限定基本平滑且连续的翼型件。 可移动叶片可以由壳体的背板可枢转地支撑,而固定叶片可以整体地设置有具有限定与背板的内表面相对的表面的盘部的固定叶片构件。 可移动叶片可以在这些相互相对的表面之间并且在这些相互相对的表面之间旋转,以改变限定在固定叶片和可移动叶片之间的喷嘴的横截面。
