Patent ID: 8813785

Claim:
A fluid selection valve comprising: a stator comprising a stator interface; a plurality of ports arranged into a plurality of port groups, wherein each port group comprises at least three ports of which one is designated as a common port and the others are designated as non-common ports, the non-common ports comprising a first non-common port and a second non-common port, wherein each of the common ports, first non-common ports and the second non-common ports are circularly arranged at the stator interface; a rotor comprising a rotor interface abutting said stator interface; a plurality of first channels, each first channel extending from an axial center of the rotor to at least a point on the rotor interface alignable with the common ports for fluid communication therewith; a plurality of second channels, each second channel extending from at least a point on the rotor interface alignable with the common ports for fluid communication therewith to at least a point on the rotor interface alignable with the first non-common ports and/or the second non-common ports for fluid communication therewith; wherein at least one of the stator and the rotor comprises a central port located in an axial center thereof; wherein the rotor is coaxially rotatable relative to the stator to configure the fluid selection valve in at least three different positions; wherein in a first position, the common ports are in fluid communication with the central port via the first channels; wherein in a second position, the common ports are in fluid communication with the first non-common ports via the second channels; and wherein in a third position, the common ports are in fluid communication with the second non-common ports via the second channels.
