WIPO Patent Application WO/2020/166426
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a supercharger casing that can be applied to a small supercharger of which the layout is restricted and that is provided with a bypass pipe having a simple structure, and a supercharger provided with said casing. A casing (10) of a supercharger (1) has formed therein an exhaust gas flow path (12) through which exhaust gas discharged from an internal combustion engine flows, and accommodates therein a turbine (30) driven by the exhaust gas flowing through the exhaust gas flow path (12). The casing (10) is provided with a bypass pipe (50) that allows communication between the exhaust gas flow path (12) on the side of an exhaust gas inlet (12A) and the exhaust gas flow path (12) on the side of an exhaust gas outlet (12B), the communication not being by way of the turbine (30). The bypass pipe (50) is configured from a straight pipe (52) that is connected to the exhaust gas inlet (12A) side and that has a straight linear flow path, and an elbow pipe (54) that is connected to the straight pipe (52) and the exhaust gas outlet (12B) side and that has a bent flow path.
