環装置。A valve body is inserted in the bypass line that bypasses the exhaust system upstream of the exhaust turbine and the intake system upstream of the compressor, and closes the bypass line in response to the biasing force of a diaphragm, thereby directing the exhaust gas to the intake system. When gas inflow is blocked and exhaust gas is recirculated as determined by the operating state of the engine, a negative pressure source that sucks the diaphragm is introduced into the diaphragm chamber, the bypass pipe is opened, and the exhaust gas is recirculated to the intake system. In an exhaust gas recirculation system for a turbocharged engine, either a negative pressure system that includes a negative pressure source that sucks in a diaphragm or an intake air introduction system that introduces air from the intake system is selected depending on the operating state of the engine. and is equipped with a valve driving device that connects the selected system and the diaphragm chamber, and supplies the air introduced into the intake air introduction system to the diaphragm chamber to block the bypass pipe except during exhaust gas recirculation. An exhaust gas recirculation device for a turbocharged engine, characterized by:
