る様にしたことを特徴とする過給圧制御装置。 The supercharging pressure of the exhaust turbocharger is taken out as a signal pressure, this signal is adjusted according to the engine exhaust pressure using a modulator with an air bleed port, and the adjusted signal pressure is applied to the pressure chamber of the wastegate valve actuator. In a supercharging pressure control device for an exhaust turbo supercharger, the supercharging pressure is controlled by controlling the opening degree of a waste gate valve according to the signal pressure. A supercharging pressure control device characterized in that a cutoff valve is provided downstream, and the cutoff valve is closed when engine exhaust pressure exceeds a set value.
