Claims

[Scope of utility model registration request]

The inlet section 11 of the turbine housing 10 is divided into left and right inlets 11a and llb by the partition wall 12, and the passage section 13 of the turbine housing 10 is divided into a passage A, llb by the partition wall 14 and 15.
A switching valve 16 for opening and closing the passage B is provided between the inlet part 11 and the passage part 13 of the turbine housing 10, so that the two adjacent passages A, B, and C are not provided.
C is the gas flow path when the engine runs at low speed, and the angle θ between these adjacent passages A and C is made small, so that the adjacent passage A
, the inner diameter D2 of the partition wall 15 between C and the other passage B is made closer to the rotor diameter D1, and the partition wall 14 between the adjacent passages A and C is lengthened along the turbine housing 10. Variable turbine housing device.
