ABSTRACT:
There is disclosed a valve comprised of a valve body defining a cavity with inlet and outlet port means opening to and leading from said valve cavity. A plug member is rotatably disposed in said valve cavity and spaced from the bottom wall thereof to define a valve chamber, with the outlet port means leading from said chamber. The plug member includes an end segment disposed in said valve cavity and provided with a pair of concave, axial elongate surface portions opening to the end face of said segment, with said concave portions being separated by convexed surface portions. The concaved surface portion cooperates with the inner wall surface of the cavity to define a pair of relatively movable channels which can be placed in communication with the inlet port means to interconnect said inlet ports with the valve chamber. The segment of the plug disposed in said valve cavity is constructed from a resilient material, and of a slightly larger diameter than the valve cavity. Accordingly, the plug segment is resiliently deformed upon assembly, with the convexed surface portions in sealing engagement with the cavity walls to effect blockage of the inlet port means, when desired, and also to maintain separation between any liquid products in said channels.
