Title: Turbo-supercharger for an internal combustion engine

Abstract

A turbo-supercharged for an engine is described comprising a supercharging compressor located in an intake system of the engine and an exhaust gas turbine located in an exhaust system of the engine for driving the compressor. The turbine includes a turbine casing and a turbine rotor rotatably supported in the turbine casing. The exhaust system of the engine has exhaust pipe means defining an exhaust passage and connected with the turbine casing. The turbine casing has exhaust gas inlet passage means for directing exhaust gas of the engine from the exhaust passage to the turbine rotor. The inlet passage means include at least a first inlet passage and a second inlet passage which are located in a side-by-side relationship with each other, valve means for closing the second inlet passage, characterized by the fact that the first and second inlet passages are opened to the exhaust passage in the exhaust pipe means respectively through first and second inlet ports which are oriented in a direction opposing exhaust gas flow in the exhaust passage. The exhaust pipe means are formed in a portion adjacent to the turbine casing with a sidewardly bulged portion. The valve means includes a valve member adaptedmore » for seating on a valve seat formed in a peripheral portion of the second inlet port for closing the second inlet port and swingable arm means for supporting the valve member swingably on the exhaust pipe means so that the valve member can be moved from a closed position seating on the valve seat against the exhaust gas flow to an open position in which the valve member is located substantially in the bulged portion.« less
