ABSTRACT:
A unitary axial multiport rotary 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 three sections, or elements, each of which is cylindrical in form. There are fluid flow channels in a rotating body, or rotor assembly, which is located inside the stator assembly and configured in a manner similar to it. The rotor assembly assumes various positions according to the cycle steps and distributes fluid flowing into and out of the valve, by means of the conduits, in a different manner in each cycle step. There are annular volumes between the rotor and stator assemblies which contain sealing means for prevention of leakage and definition of flow passages.
