摘要： This disclosure is directed to an electromechanical servovalve having an electrical coil or winding movably mounted relative to a magnet so that when the winding is energized by an electric current, it interacts with the magnetic flux generated by the magnet to shift a valve member of an associated valve between operative and inoperative position. The arrangement is such that the valve member functions as the bearing for the movable coil or winding so as to render the servovalve lighter and faster in operation. The valve member is biased toward its neutral or inoperative position by a pair of opposed springs, one of which can be readily adjusted to vary the biasing force of the springs acting upon the valving member.

摘要： The moving drive portion of the force motor for an electromechanical servovalve is mechanicalkly constrained by slide bearing located on either side of the moving part to prevent it from rubbing against nonmoving parts, in turn, causing early failure and reliability problems. The connection between the force motor and the servovalve is adjustable to allow both the force motor to be electrically centered and the servovalve to be mechanically centered.

摘要： A direct-operated servo valve which exhibits stable damping characteristics. The servo valve is characterized in that a viscous fluid is charged in the gap between a stator and a movable element. The velocity of a valve member is detected and a feed back the velocity signal is obtained by this detection so as to enable a damping of the motion of the valve member.
