切替弁。 A diaphragm upper chamber and a diaphragm lower chamber defined by a diaphragm, a valve body interlocked via the diaphragm and a valve stem, holding the diaphragm and supporting the valve stem in an airtight manner,
It includes a valve housing in which a boost pressure relief chamber and a valve seat are formed, and a spring that biases the valve body toward the valve seat, and the intake pressure supplied to the diaphragm upper chamber and the excess pressure in the supercharging passage are provided. A downstream side of the compressor, which opens against the spring force of the spring in relation to supply pressure, and releases the supercharging pressure in the supercharging passage through the supercharging pressure relief chamber, which opens the supercharging pressure relief chamber. In a boost pressure switching valve for a turbocharged internal combustion engine configured to release air from a passage to a passage on the upstream side of a compressor, the other end of a ventilation orifice for introducing atmospheric air, one end of which is open in the lower chamber of the diaphragm, is connected to the passage on the upstream side of the compressor. A supercharging pressure switching valve for a turbocharged internal combustion engine, characterized in that it is opened at .
