ABSTRACT:
A rotary spool is provided with four axially extending grooves in its outer peripheral surface. Alternating ones communicate with opposite ends of the spool and terminate short of the respective other ends. Each spool end communicates with a respective chamber. Each chamber is communicated to a check valve which may be opened by pressure in the chamber, or opened by a respective cam on the spool. By preference the spool has an operating handle, which, when in neutral, communicates the inlet with an outlet, and when rotated 45.degree. clockwise or counterclockwise communicates the inlet with a respective check valve and communicates the conduit beyond the other check valve with the outlet, while the respective cam holds said other check valve open.
