Three-position, self-centering valve for control of fluid actuators and the like |
摘要 |
A pair of fluid valves are formed in a common valve body. Movable pistons in the respective valves are normally biased by the fluid pressure input to closed positions whereby button-like or rod-like extensions of the pistons protrude through a top wall of the valve body to urge a pivotal valve operator to a neutral centered position. By manually pivoting the operator against one or the other of the extensions the respective pistons may be moved to open the respective valves.
