PROBLEM TO BE SOLVED: To provide an inexpensive exhaust recirculating a flow control valve in a simple structure. SOLUTION: The exhaust recirculating flow control valve for an engine comprises an inlet passage 17 for taking in a part of an exhaust gas in an exhaust passage 3 of the engine, first and second supply passages 18 and 19 which are arranged both sides of the inlet passage 17 and supply the exhaust gas flowing from the inlet passage 17 to an intake passage 2 of the engine, first and second openings 20 and 21 for respectively connecting the first and second supply passages 18 and 19 with inlet passage 17, and a valve 25 in which first and second valve bodies 22 and 23 for respectively opening and closing the first and second openings 20 and 21 are coaxially and integrally formed. Change rates of the gas flow against a lift amount of the valve 25 are respectively different on the first and second valve bodies 22 and 23 of the valve 25. COPYRIGHT: (C)2008,JPO&INPIT
