過給圧制御装置。A diaphragm connects an exhaust bypass passage to bypass the exhaust turbine of the turbocharger and pass part of the exhaust gas, a passage opening/closing valve that opens and closes the passage, a pressure chamber communicating with the intake passage on the downstream side of the intake compressor, and an atmospheric chamber communicating with the atmosphere. In a boost pressure control device for a turbocharged internal combustion engine, the boost pressure control device for a turbocharged internal combustion engine is equipped with a diaphragm actuator that controls opening and closing of the passage opening/closing valve according to the displacement of the diaphragm based on the pressure difference between the two partitioned chambers. A control means is provided for controlling the boost pressure downstream of the intake compressor of the turbocharger to mix it with the atmosphere, reduce the pressure, introduce it into the atmospheric chamber of the actuator, and maintain the atmospheric pressure at a substantially constant value. Features: Boost pressure control device for turbocharged internal combustion engines.
