Abstract
PURPOSE: To stop returning in the exhaust-gas recirculation control device of an engine when a primary-side throttle valve is opened almost to the full by regulating the amount of negative pressure to the negative pressure chamber of a return control valve by means of a switch valve operated by the difference of negative pressures between the first and the second Venturi tube.
CONSTITUTION: A suction passage 2 consisting of a primary-side Venturi tube 2a and a secondary-side Venturi tube 2b is connected to an engine 1. The suction passage 2 is connected to an exhaust passage 3 via an exhaust-gas recirculation passage 4 provided with an exhaust-gas recirculation control valve 5, while the suction negative pressure in the downstream of a throttle valve 8a is transmitted to a negative pressure chamber 5a of the control valve 5 via the first and the second control valve 17, 19, and a storage tank 11. These two control valves 17 and 19 are switched over by a switch valve 7, into which negative pressures in the primary and the secondary-side Venturi tube 2a and 2b introduced for operating the valve 7 by their difference.
