Abstract
PURPOSE:To improve the turbine efficiency in a low speed revolution region by installing a movable member at the outlet of a nozzle part used in the high speed revolution region of an engine among a plurality of nozzle parts arranged in a plurality of scroll chambers formed on a turbine vane wheel. CONSTITUTION:The inside of a scroll of a turbine vane wheel fixed onto a same revolution axis of a compressor vane wheel is divided into a plurality of scroll chambers 1 and 3 by a partitioning wall 5, and the first nozzle part 2 is formed oppositely to a turbine vane wheel inlet part 6 in the chamber 1. While, in the combustion chamber 3, the second nozzle part 4 is formed on the side surface of the turbine vane wheel inlet part 6. In this case, in a turbine casing 7 in the nozzle part 4, a movable member 8 is arranged integrally with a disc 9 which can shift in the direction of a revolution axis in a cylinder chamber 10 having a pressure hole 11. Therefore, in the engine low speed revolution region, the communication between the chamber 3 and the inlet part 6 is cut off.
