ABSTRACT:
A unitary disc-axial multiport valve capable of accomplishing the simultaneous interconnection of a plurality of conduits in accordance with a previously determined cycle, where any conduit communicates with no more than one other conduit at any one cycle step, or valve index position. The conduits to be interconnected are attached to a hollow stationary body, or stator assembly, which is comprised of two sections, or elements, one being cylindrical in exterior form and the other having a disc-like form with a central opening and being joined to the cylindrical element at one end in a flange-like manner. There are fluid flow paths in a rotating body, or rotor assembly, which is located partially inside the stator assembly, extending through the central opening in the discular element of the stator. The form of the rotor assembly is similar to that of the stator assembly. The rotor assembly assumes various positions according to the cycle steps and distributes fluid flowing into and out of the valve in a different manner in each cycle step. There are spaces between the rotor and stator assemblies which contain sealing means for prevention of leakage and definition of flow passages.
