Abstract: A rotary valve comprises a bushing and a cylindrical spool rotatably received by the bushing. The rotary valve avoids redundant control edge pairs by having exactly one first supply edge pair (P-C1) for controlling a first fluid supply path, exactly one second supply edge pair (P-C2) for controlling a second fluid supply path, exactly one first return edge pair (C2-R1) for controlling a first fluid return path, and exactly one second return edge pair (C1-R2) for controlling a second fluid return path. A first angle between the first supply edge pair and the first return edge pair, and a second angle between the second supply edge pair and the second return edge pair, are each greater than or equal to 120 degrees and less than 180 degrees. Geometric simplicity is achieved by tolerating a limited degree of force imbalance in valve operation.
