<p><P>PROBLEM TO BE SOLVED: To provide a turbine capable of reducing the unevenness in flow speed at each throat, regardless of the flow rate of fluid that can prevent capacity deterioration. <P>SOLUTION: The turbine is provided with: a turbine rotor 80, having turbine blades 82; a turbine housing 60 housing the turbine rotor 80, with the cross section of a scroll part 100 formed between the turbine rotor 80 and the housing gradually decreasing; a plurality of fixed vanes 102 fixed on curvature partitioning the scroll part 100 into an inner circumferential scroll part 66 and an outer circumferential scroll part 68; the throats 101 formed between the adjoining fixed vanes 102 for communicating the inner circumferential scroll part 66 with the outer circumferential scroll part 68; and a selector 90 for switching a passage in the turbine housing 60 to the inner circumferential scroll part 66 or the inner circumferential scroll part 66 and the outer circumferential scroll part 68, and the throat 101 is formed with its passage area reduced toward downstream of the scroll part 100. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
