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 cycle step, or valve index position. The conduits to be interconnected are attached to a stationary body, or stator assembly, having channels in it which communicate between the conduits and flow paths in a rotating body, or rotor assembly, which assumes various positions according to the cycle steps and distributes fluid flowing in the conduits in a different manner in each cycle step. In one embodiment, the rotor assembly is comprised of two parallel plates, or discs, and is sandwiched between two biplanar parallel plates which comprise the stator assembly. Crossover pipes extend between the rotor plates.
