Abstract
An exhaust gas recirculation system for an internal combustion engine employs a vacuum actuator for a control valve in the exhaust gas recirculation passageway. A suction conduit to the actuator contains a magnetic valve for venting the suction conduit to atmosphere. The operating means for the magnetic valve includes a vacuum switch responsive to suction pressure in the engine intake passage modified by atmosphere pressure compensation means. A second magnetic valve responsive to engine speed also vents the suction conduit to atmosphere.
