ABSTRACT:
A self-responsive fluid means for anti-cavitation, such as when a fluid motor is rotating in a manner beyond that induced by the fluid pressure fed thereto, and thus the motor itself acts in the nature of a pump to produce a cavitation effect. Thus, there is a fluid motor, a valve controlling flow thereto, a pump, and an additional valve which directs the exhaust from the fluid motor and back to the motor itself, under certain conditions of operation, all to avoid the cavitation effect. The latter valve includes two fluid inlet openings and a movable closure which controls fluid flow to a fluid outlet opening; and pressure relief valve are incorporated in that valve and thus permit and control flow to the reservoir when pressure is at a certain magnitude.
