<p>PURPOSE:To improve efficiency of a turbine, by providing an engaging part, which seals a partition between the other end of guide vanes and a scroll internal wall surface opposed to said end of the vanes, and eliminating exhaust gas which is allowed to directly flow into an impeller detouring around the guide vanes. CONSTITUTION:A nozzle 9 is formed in the point end of a tubular member 18 mounted to the side surface of a scroll 8 from the back side of a turbine impeller 10. Plural sheets of guide vanes 17, protruding in the axial direction from a curved surface 18a of the scroll 8, are formed spacing a predetermined distance. Each point end of the guide vanes 17 is connected by an annular member 19. The scroll 8 has an annular partition 12 in the inside, and a scroll chamber is divided into two parts by said partition 12. The internal peripheral end of the annular partition 12 extends to the annular member 19 in the point end of the guide vanes 17, and both adapted surfaces from a faucet joint fitting part 19b.</p> |
