。 A bypass control valve is installed in a bypass passage that detours around the turbocharger, and the bypass control valve is connected to a diaphragm actuator to apply boost pressure to a first diaphragm chamber on one side of the diaphragm and to a second diaphragm chamber on the other side of the diaphragm. In a device that controls the boost pressure by applying atmospheric pressure, the first diaphragm chamber connects the first boost pressure port downstream of the compressor of the turbocharger and the second boost pressure port in the middle of the compressor via the first switching valve. The second diaphragm chamber is switchably connected between atmospheric pressure and an intake pipe pressure port downstream of the air cleaner and upstream of the compressor via a second switching valve. A supercharging pressure control device for an internal combustion engine with a turbocharger.
