PURPOSE:To partition, make independent and treat an outlet for a sub-gas, an outlet for a main gas and a gas discharged from both outlets completely while lowering the pressure (the back pressure of an engine) of a turbine outlet. CONSTITUTION:The outlet 8 for the sub-gas into which a bypass valve mechanism 5-a is encased is formed near the outlet 7 for the main gas. A turbine housing section direct partition section 10 as shown in broken lines are formed in order to close a bypass 9 communicating the outlet 8 for the sub-gas and the outlet 9 for the main gas and partition and make independent both outlets. Since the shaft section 11 of the bypass valve mechanism 5-a is inserted into the hole 12 of a housing section, it is difficult to form the partition section 10 as shown in broken lines, thus partitioning the outlet 7 for the main gas and the outlet 8 for the sub-gas through a method pressing in a cylindrical partition member 31. |
