Abstract

PURPOSE: To reduce a number of control signals, by operating the exhaust gas return cut signal of exhaust gas return system, when highly loaded the engine, with a vehicle speed signal and an atmospheric vent orifice used.
CONSTITUTION: A negative pressure within a negative pressure path 15 is controlled by the action of a negative pressure regulator valve 20, an orifice 30 of prescribed diameter opening and a solenoid open-close valve 31 provided repectively in two atmospheric vent paths 16, 17 connected to the negative pressure path 15. With this controlled negative pressure conducted into a negative pressure operating chamber 13, in accordance with the level of this negative pressure and through a diaphragm 9, is controlled a path area due to a valve level 3, that is, the exhaust gas return flow rate. When traveling at high speed, with a vehicle speed switch 35 turned ON to make a conduction to energize the sloenoid open-close valve 31, 32, the atmospheric vent path 17, 33 is made open to the amosphere. Accordingly, a Venturi negative pressure in a Venturi negative pressure operating chamber 24 is weakened by the atmosphere with the return flow rate reduced.
