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.

Abstract: A unitary multiport rotary disc 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 valve index position. It is particularly useful where such plurality of conduits may be divided into three separate groups according to their function and it is necessary to interconnect the conduits in accordance with a relationship among the groups. The conduits to be interconnected are attached to the bottom of a discoid stationary body, or stator, having channels in it which communicate between the conduits and flow paths in a discoid rotating body, or rotor, which assumes various positions according to the cycle steps and distributes fluid flowing in the conduits in a different manner in each cycle step.

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 exterior form. There are fluid flow paths in a rotating body, or rotor assembly, which is located inside 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.

There are annular volumes between the rotor and stator assemblies which contain sealing means for prevention of leakage and definition of flow passages.
