とする過給圧制御装置。 A supercharging pressure control device for a turbocharger that controls the opening and closing of a wastegate valve according to the magnitude of the pressure introduced into a variable pressure chamber in a casing, which controls the pressure in the intake passage downstream of the compressor to the variable pressure chamber. A valve body is provided in the middle of the passage to form a port that can communicate with the atmosphere and open and close this port, and this valve body is biased in the direction of closing the port by the pressure in the exhaust passage. Boost pressure control device.
