制御弁。[Claims for Utility Model Registration] In order to control the negative pressure from the intake pipe that is applied to the exhaust recirculation valve provided in the middle of the pipe that communicates the exhaust pipe and intake pipe of the internal combustion engine, An exhaust gas recirculation control valve that operates depending on a pressure between a fixed orifice provided and the exhaust gas recirculation valve and a venturi negative pressure of the carburetor to control the amount of atmospheric air introduced into the exhaust gas recirculation valve. The reflux control valve is an exhaust valve formed by the exhaust pressure chamber composing members on one side of the first diaphragm which is held between the body and the exhaust pressure chamber composing members, and through which the pressure between the exhaust recirculation valve and the fixed orifice is guided. a pressure chamber, (b) an atmospheric pressure chamber formed by the other side of the first diaphragm, the body, and one side of a second diaphragm held between the body and the side wall and into which the atmosphere is introduced; (C) the second diaphragm; a negative pressure chamber formed on the other surface of the diaphragm and the side wall to which venturi negative pressure is introduced; (d) a negative pressure chamber that cooperates with the side wall to sandwich the inner layer of the second diaphragm and protrudes into the atmospheric pressure chamber; (e) an air introduction passage formed in the cover that is opened and closed by a seat fixed to the other side of the first diaphragm, extends in the direction of movement of the seat, and is connected to the exhaust gas recirculation valve; ) a metal fitting that connects the first diaphragm and the diaphragm; (g) a spring that is disposed in the atmospheric pressure chamber and urges the seat toward the exhaust pressure chamber. Gas return flow control valve.
