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. The stator has two rows of ports which are arranged in two concentric circles in addition to a number of fluid-containing grooves extending circumferentially 360.degree. around the stator.
