させたことを特徴とするエンジン過給機の制御装置。゛A supercharging control valve is provided upstream of the throttle valve in the intake passage of the engine, and a supercharging passage is formed by bypassing the supercharging control valve. A driven supercharger is provided, and the supercharging control valve is opened and closed by an actuating body that responds to a pressure difference within the actuator, and each pressure chamber in the actuator divided by the actuating body is controlled by a pressure difference. A switching valve that is connected to a pressure detection port opened downstream and upstream of a throttle valve in the intake passage through an introduction path, and is operated in response to the opening of the throttle valve exceeding a set value. The supercharging control valve is closed by bringing the pressure introduction passages into communication with each other, and the opening degree of the supercharging control valve when fully opened is approximately equal to the set opening degree of the throttle valve. Control device for engine supercharger.゛
