ABSTRACT:
This disclosure is directed to an electromechanical servovalve having a movable electrical coil or winding circumscribing a solid permanent magnet and disposed so that when the winding is energized by an electric current, it interacts with an intensified magnetic flux generated by the permanent magnet to shift a valve member of an associated valve between an operative and inoperative position. The arrangement is such that the valve member also functions as the sole bearing support for the movable coil whereby the servovalve is rendered lighter and faster in operation.
