式過給機。 The air is compressed and discharged through a suction stroke section, a compression stroke section, and a discharge stroke section by a compression mechanism built into the casing, and the discharged air is passed through a bypass flow path to the suction side while supercharging the engine. In a mechanically driven supercharger, the casing is located at a position spanning from the suction stroke section to the compression stroke section, so that the air flowing from the suction stroke section to the compression stroke section is returned to the suction side. 1. A mechanically driven supercharger characterized in that a bypass port is provided to open and close the bypass port, and the bypass port is provided with an on-off valve for opening and closing the bypass port.
