Abstract
A multiple channel selector valve includes a stator and a rotor that is rotatable with respect to the stator. The rotor face includes first and second fluid flow paths for transferring fluids to selected sets of passages in the stator. The fluid flow paths in the rotor face are specifically configured to accommodate high fluid flow rate regimes while reducing flow restriction.
Claims16
A multiple channel selector valve, comprising:
- a stator having a front face, a dynamic face, and a plurality of passages extending through the stator to fluidically connect the front face and the dynamic face, the plurality of passages including first passages extending between respective first openings in the dynamic face and first ports in the front face, second passages extending between respective second openings in the dynamic face and second ports in the front face, an intake passage extending between an intake opening in the dynamic face and an intake port in the front face, and an outlet passage extending between an outlet opening in the dynamic face and an outlet port in the front face;
- and
- a rotor rotatable with respect to the stator about a rotational axis and having a rotor face configured to sealingly engage with the dynamic face of the stator, the rotor face including a first fluid flow path for fluidically coupling the intake opening to selected ones of the first openings, and a second fluid flow path for fluidically coupling the outlet opening to selected ones of the second openings, the second fluid flow path having a transfer portion and a relief portion, the transfer portion having a proximal end that transitions to the relief portion and a distal end, with the transfer portion being flared from the distal end to the proximal end by between about 10-75°, and the relief portion being annularly arranged about the rotational axis by at least 30°.
A multiple channel selector valve, comprising:
- a stator having a front face, a central axis, and a generally opposed dynamic face including a plurality of first openings arranged in a first circumaxial pattern about the central axis, and a plurality of second openings arranged in a second circumaxial pattern about the central axis;
- and
- a rotor rotatable with respect to the stator about a rotational axis coincident with the central axis and having a rotor face configured to sealingly engage with the dynamic face of the stator, the rotor face including a first fluid flow path and a second fluid flow path, the first fluid flow path extending from the rotational center of the rotor face to a first end to selectively fluidically connect to any one the first openings, and the second fluid flow path having a transfer portion and a relief portion, the transfer porting being flared from a distal end in fluid communication with any one of the second openings to a proximal end to by between about 10-75°, and the relief portion being annularly arranged about the rotational axis by at least 30°.
