Abstract

PURPOSE: To release the operation quickly by providing a check valve for conducting with the air in the negative pressure path of an exhaust gas recirculator, then providing the air into the recirculator.
CONSTITUTION: An exhaust gas system (not shown) and a suction system 2 are conducted through a recirculation path 3 having an exhaust recirculation valve 5, to recirculate a portion of the exhaust gas through a suction system 2. The suction negative pressure at the downstream of a throttle valve 12 is provided through a negative pressure paths 8, 8' into the negative pressure chamber 52 of the control valve 2. A pressure regulating valve 7 for regulating the pressure by the exhaust pressure from a pressure chamber 30 is provided in the negative pressure path 8 to vary the negative pressure. The negative pressure path 8 is conducted through a check valve 4 to a sensing port 14 immediately above the throttle valve when performing the opening/closing, where during deceleration the air is provided from port 14 through the check valve 4 into the path 8 to disable the control valve 5.
