ABSTRACT:
A direct drive servovalve having a stator and rotor mounted upon a housing within which a spool valve is reciprocally disposed for engagement with the rotor and movement thereby in response to the application of appropriate electrical signals. The stator assembly is adjustable and after appropriate adjustment there is provided a retainer means secured to the closed end of an isolation tube for clamping the stator assembly in place relative to the rotor assembly of the moored motor. The clamping assembly includes an annular member having a downwardly depending skirt which engages the stator. The annular member is held in place by a retainer ring threadably secured to the outer surface of the isolation tube or alternatively behind fasteners which are threadably received by the closed end of the isolation tube. A separate non load bearing housing cover is positioned over the motor.
