ABSTRACT:
A rotary valve for pressure fluid distribution to accomplish a sequential delivery of the pressure fluid to a series of outlets, in which a housing contains a stator having a semi-cylindrical face surface through which outlet ports open, and an elongated cylindrical rotor mounted for rotation adjacent the stator face, the rotor having a series of flow directing passages positioned to direct pressure fluid supplied to the interior of the housing through each of the outlet ports at least one at a time and in a predetermined sequence during rotation of the rotor. The arrangement of the fluid flow passages in the rotor, and the angular spacing of the passages around the circumference of the rotor is selected to minimize or avoid the destructive effect of water hammer by establishing a flow through a portion of a trailing port before a leading port effectively closes off the fluid flow.
