Abstract

PURPOSE: To obtain recirculation of an exhaust gas in a proper quantity by controlling negative pressure at the intake tube, which is to control an exhaust gas recirculation control valve of an internal combustion engine, using a negative pressure modulator valve operated by venturi negative pressure.
CONSTITUTION: The intake and exhaust lines of an engine are put into communication by a recirculation passage 28 having an exhaust gas recirculation control valve 2, through which a part of exhaust gas is fed back to the intake line. Into a working chamber 17 of thid control valve 2, intake negative pressure in the neighborhood of a throttle valve is introduced through a negative pressure passage 11 having a negative pressure regulator valve 3. This negative pressure is regulated by a negative pressure modulator valve 1 which is controlled by the negative pressure at venturi part 22. A regulator valve having an obstacle 33 adjusts the openings of the first and second ports 4, 13 and the outlet port 15 of the valve 1 in accordance with the magnitude of the negative pressure introduced into the negative pressure chamber 20, and introduction of air in the working chamber 17 makes correction of this magnitude of negative pressure.
