Classification: CPC F  B | IPC B  F

Claim 0:
1. A rotary valve comprising:
a. a rotor 10 comprising an outer face 13 and a rotor valving face 12 opposite the outer face 13 and a pair of apertures 41, 42 through the rotor valving face 12;
b. a stator 50 having a stator face 52 having a plurality of stator ports 53 in the stator face, each one of the plurality of stator ports 53 in communication with a fluid passage 54 wherein the rotor valving face 12 is spaced apart from the stator face 52 while the rotary valve is in a storage condition;
c. a retention element 90 comprising a retention ring 91 and a biasing element 96 biasing the rotor and stator towards one another;
wherein the rotary valve is maintained in the storage condition while a portion of the retention ring is engaged with a portion of the rotor; and
wherein a relative motion between the rotor and the stator disengages the portion of the retention ring engaged with the portion of the rotor to produce a fluid tight arrangement between the rotor valving surface and the stator face.
