ABSTRACT:
A turbo-supercharger for an engine including a turbine casing of which scroll is formed with two exhaust gas inlet passages. The turbine casing has an inlet end surface connected with the outlet end surface of an engine exhaust pipe. The inlet passages are opened to the inlet end surface of the turbine casing respectively through inlet ports which are arranged in side-by-side relationship. A valve mechanism is provided to close one of the inlet ports under a low speed engine operation. The valve mechanism has a valve member adapted to seat on the inlet end surface and a swingable arm mounted on the exhaust pipe for moving the valve member. The exhaust pipe is formed with a sidewardly bulged portion where the swingable arm is supported. The swingable arm and the valve member are substantially received in the bulged portion in the open position.
