ABSTRACT OF THE DISCLOSURE An exhaust gas recirculation valve driven by an electric motor. The valve comprises a housing having an inlet port and an outlet port, a valve member disposed within said housing, an electric motor attached to the upper portion of said housing, a changing means for changing the rotation of said electric motor into the vertical movement of said valve member, said changing means being disposed between the shaft of said electric motor and a valve rod. The valve member is operated by said electric motor through the intermediary of said changing means. Therefore, the valve can be controlled delicately independent of the engine manifold vacuum. The valve may be incorporated into an electronic fuel injection system adapted to calculate the amount of fuel supply to an internal combustion engine by means of a control unit so as to obtain an optimum air- fuel mixture or air-fuel ratio. In this case, an actuating signal calculated on the basis of said amount of fuel supply and the information of sensors is given to said electric motor so as to obtain an optimum opening of the valve. Therefore, the valve can be controlled very accurately.
