とするモータを用いた制御弁。 A control comprising: a housing formed with a valve housing and a boat opening into the valve housing hole; and a spool valve that is fitted into the valve housing hole so as to be slidable only in the axial direction and controls the opening degree of the port. In the valve,
a cylindrical part formed coaxially at one end of the spool valve and having a ball holding hole penetrating in the radial direction; a cylindrical part supported by the housing so as to be rotatable only coaxially with the spool valve; and a threaded groove formed in the tip part; The tip end is held in a ball screw shaft inserted into the inner periphery of the cylindrical part with a slight gap, a cylindrical retainer provided on the outer periphery of the cylindrical part, and the ball holding hole. A control valve using a motor, characterized in that the step motor has a ball that engages the thread groove and the retainer on the inner and outer sides thereof, and a rotor shaft that is supported by the housing and coupled to the ball screw shaft. .
