流装置。 A pressure-operated recirculation control valve is provided in the exhaust gas recirculation passage connecting the intake system and the exhaust system in an internal combustion engine with a supercharger, and the closed position of the pressure chamber of the recirculation control valve and the throttle valve in the intake system A sensing port located slightly upstream is connected to the sensing port through a pressure transmission passage such that when the pressure at the sensing port increases to the vacuum side, the reflux control valve opens.
An exhaust gas recirculation device comprising a check valve that opens only in the direction toward the sensing port in the pressure transmission passage, characterized in that the pressure chamber in the recirculation control valve is throttled and communicated with the atmosphere through an orifice. Exhaust gas recirculation system for internal combustion engines with superchargers.
