を備えた過給機付エンジン。 The two rotors, which are rotatably supported by bearings in the pump housing, rotate while meshing with each other while maintaining a predetermined clearance between them and the inner peripheral surface of the housing, and each rotation draws a fixed volume of fluid from the suction side. In a supercharged engine equipped with a Roots pump that sucks and discharges air on the discharge side, an annular space formed on the circumferential surface of the rotor shaft and between the end surface of the rotor and the seal portion of the bearing is used as an air introduction passage. The atmosphere introduction passage is provided with a control valve that connects to the atmosphere through the air supply passageway and opens and closes depending on the operating conditions of the engine, and further includes an atmosphere introduction passage that connects the annular space portion of the atmosphere introduction passage with the control valve. A supercharged engine equipped with a roots pump, characterized in that the roots pump communicates with a space formed by the outside of the housing and the outside of the bearing.
