An electric motor-operated flow control valve (10), particularly for refrigeration fluids, having a valve body (14) with intake (15) and discharge (16) ports and a movable plug element (17), and a motor section (11) for actuating and adjusting the movable plug element (17). The rotor part (13) of the motor of the valve (10) is supported rotatably in a hermetic capsule (19) which is fixed to the valve body (14), is axially fixed, and is coupled with a screw-and-nut coupling to the movable plug element (17), which plug element (17) is further constrained by the valve body (14) to perform only axial translatory motions. <IMAGE> |
