ABSTRACT:
A valve has a first set of passages for simultaneously connecting an inlet of a first chamber hydraulically to a source of fluid under pressure and an outlet of a second chamber hydraulically to a venting tank and a second set of passages for simultaneously connecting an inlet of the second chamber hydraulically to the source of fluid under pressure and an outlet of the first chamber hydraulically to the venting tank. The sets of passages are sequentially repositioned to alternately cyclically connect and interrupt hydraulic communication through them. The first and second sets of passages are so configured in relationship to the inlets and outlets that flow through one set is completely terminated only after flow in the other set is initiated.
