ABSTRACT:
A rotary servo valve includes a valve body having a longitudinal bore therethrough. A sleeve fits into the bore. The wall of the sleeve is perforated by two groups of port openings, each group includes a plurality of sets of radially-disposed ports. In each group, the central longitudinal axis of one set of ports is radially displaced from the central longitudinal axis of one other set of ports by a preselected angular displacement. At least a third set of ports in one group is in continuous fluid communication with a source of pressurized fluid; at least a third set of ports in the other group in continuous fluid communication with a return sump. A hollow rotary control member consists of two internal chambers. Each chamber includes a number of sets of apertures that are radially disposed around the walls of the chambers, spaced-apart by a preselected angular separation. A torque motor means is furnished to rotate the control member between two opposite angular positions with respect to a null position, thereby to apply power to cause a hydraulic actuator to operate in a desired manner.
