ABSTRACT:
A rotor balancing arrangement is provided for use in a distribution valve to ensure hydrostatic balancing of a rotor located in the distribution valve. Some balancing arrangements provide areas equally spaced around the peripheral surface, each being exposed to the same pressure, however, they are limited to valves which rotate only through a limited arc of rotation. Other valves which rotate provide balancing grooves around portions of the peripheral surface but do not provide any control for the pressure that migrates axially in both directions along the peripheral surface of the rotor. In the subject arrangement, pressure fields of a predetermined size are located on a peripheral surface of a rotor circumscribing first and second outlet ports which open to opposite sides of the rotor. The size of the pressure fields is determined by the relationship of the diametrical clearance between the rotor and a bore with respect to the operating pressure of the system. This arrangement ensures that the differential forces acting on opposite sides of the rotor are minimized thus eliminating rotor sticking.
