Abstract
A rotary valve assembly for use in a process provides fluid communication and enables variable conduit interconnection and flow passage. Process cycle time is variable by means of rotational speed of through one or more apertures of a third valve member and respective alignment with one or more apertures of a first valve member and one or more apertures of a second valve member. Process step time is variable by means of adjustable position and variable alignment of aperture(s) of the first valve member and the second valve member. The rotary valve assembly provides for gradual transition and flow passage between process steps, flow metering, mixing, reversal, or any combination thereof. Process systems including the rotary valve include an adsorption process, humidity control process, heat pump process and/or water purification process among others.
