ーボチャージャ。In order to drive and control the compressor installed in the intake passage to the engine, there is a turbine installed in the exhaust passage of the engine, a waist passage branched from the exhaust passage on the upstream side of the turbine, and the waist passage. A waste gate valve interposed in the waste gate valve, a differential pressure responsive actuator for opening and closing the waste valve, and a control fluid supply source for supplying control fluid to the actuator according to the discharge pressure of the compressor, and the control fluid supply source to the actuator. In order to perform switching control between the opening operation of the wastegate valve by supplying upstream control fluid and the closing operation of the wastegate valve by stopping the supply of the same control fluid, the control fluid supply source and the differential pressure responsive actuator are connected. A turbocharger with a waste gate valve, characterized in that a boost valve that opens when the pressure of the control fluid from the control fluid supply source reaches a predetermined pressure or higher is interposed in the piping between the turbochargers.
