ABSTRACT:
A valve assembly and overall system provides selective fluid flow switching and communication between a plurality of flow conduits. The valve assembly includes two valve members which have respectively engaged surfaces which are relatively rotatable to provide the valving action. A first valve member has a plurality of through apertures for respective communication with the flow conduits and a second valve member includes flow passage means for selectively interconnecting at least two of the apertures through the first valve member in order to enable fluid flow therebetween. Drive means is provided for driving continuous relative rotation of the valve members in order to enable rotationally cycled interconnection and fluid flow through the interconnected apertures. The valve assembly can be employed, for example, to provide switching of air intake between dual air separation vessels which provide concentrated oxygen, so that air can be processed in one of the vessels while the other processing vessel is regenerated to purge the waste gases for further oxygen separtaion, and modulated flow switching is performed in a continuous, cycled manner with simple and reliable cycle frequency.
