気ガス還流路を連通ずる排気ガス還流装置において、吸
入管負圧を導く負圧通路とベンチュリー負圧を導く負圧
通路とを調圧装置に連通して特に高負荷時天きい負圧を
確保するように構成し、該調圧装置からの負圧通路を機
関運転状態に応じて負圧をリークさせるソレノイドバル

とを特徴とする排気ガス還流装置。In an exhaust gas recirculation system that communicates an exhaust gas recirculation path with an EGR valve from the exhaust system of the engine body to the intake system, the negative pressure path that leads to the suction pipe negative pressure and the negative pressure path that leads to the venturi negative pressure are connected to a pressure regulator. A solenoid valve that communicates with the valve to ensure top negative pressure especially at high loads, and that leaks negative pressure from the negative pressure passage from the pressure regulating device depending on the engine operating state, and a solenoid valve for controlling the EGR valve. An exhaust gas recirculation device characterized by communicating with a negative pressure chamber.
