ABSTRACT:
A switching valve having a bottom plate, an intermediate plate and a top plate. A distributor rotatably mounted in the intermediate plate. The bottom plate has an upper surface, and the distributor has a lower surface which interface with each other. The bottom plate has an inlet and an outlet spaced from each other and each having an inlet conduit extending from the inlet to the upper surface of the bottom plate and an outlet conduit extending from the outlet to the upper surface of the bottom plate. The distributor having an inlet conduit, an outlet conduit and a connecting conduit connecting the two together. The distributor inlet conduit is in communication with the bottom plate inlet conduit. The distributor outlet conduit is spaced from the distributor inlet conduit a distance equal to the space between the bottom plate outlet conduit and bottom plate inlet conduit so that rotation of the distributor to a predetermined position places the distributor outlet conduit in alignment with the bottom plate outlet conduit to permit fluid to flow from the inlet to the outlet and rotation of the distributor to another position disconnects the distributor outlet conduit from the bottom outlet conduit plate to prevent flow of the fluid. An O-ring seal in the bottom plate on each side of the bottom plate outlet conduit. An O-ring seal is provided in the top and bottom surfaces of the intermediate plate.
