た過給圧制御装置。 A bypass is separated by a diaphragm from an exhaust passage for supplying exhaust gas from the combustion chamber of the engine to the turbine of the turbocharger to an exhaust passage downstream of the turbine, and introduces supercharging pressure from the compressor of the turbocharger. A device for controlling the opening and closing of a waste gate valve driven by a diaphragm actuator having a first pressure chamber opened to the atmosphere and a second pressure chamber opened to the atmosphere, thereby controlling the supercharging pressure from the compressor, Control for extracting supercharging pressure to be introduced into the first pressure chamber of the actuator from a plurality of locations downstream of the compressor including the compressor and selectively introducing it into the first pressure chamber according to environmental conditions and/or operating conditions. Boost pressure control device with means.
