Apparatus for recirculating exhaust gases

An apparatus for recirculating exhaust gases, wherein an exhaust gas recirculating passage provides communication between the intake and exhaust passages of an internal combustion engine. A constriction is provided in the passage, and a control valve is provided in the passage downstream of the constriction. A negative control pressure passage introduces a negative control pressure from a port in the intake passage to the control valve. A pressure chamber is interposed between the constriction and the control valve, which pressure chamber has a pressure therein which is substantially equal to atmospheric pressure when the control valve is opened and to that in the exhaust passage when the control valve is closed. A first operating valve opens the negative control pressure passage to the atmosphere when the pressure in the pressure chamber becomes substantially atmospheric. A second operating valve, which is responsive to the amount of sucked air flowing through the intake passage, opens the negative control pressure passage to the atmosphere when the pressure in the intake passage exceeds a predetermined negative pressure.
