Claims

[Scope of utility model registration request]

The inside of the turbine housing body 10 is divided into two partition walls 11.
．． 12 into passages A, C, and B, and the inlet of the turbine housing main body 10 is divided into inlets A', C', and B' by two partition walls 13 and 14, and one partition wall 11 and one partition wall 13. In between, a first valve 15 is provided which communicates the inlet A', passage A1, population C', and passage C when the engine is running at high speed, and communicates between the inlets A', C' and the passage A when the engine is running at low speed. 12 and the other partition wall 14, there is an inlet C' at high engine speed and a passage B'.
The variable vaneless turbine engine is characterized in that it is provided with a second valve 16 which communicates the inlet B' with the passage B and communicates the inlet B' with the passage C when the engine is running at low speed.
