A recently granted patent (Publication Number: US11920700B2) discloses a rotary valve design that includes a rotor with apertures, a stator with stator ports, and a retention element with a retention ring and biasing element. The rotary valve is maintained in a storage condition by engagement between the retention ring and the rotor, with relative motion between the rotor and stator facilitating a fluid-tight arrangement between the rotor valving surface and the stator face. The transition from storage to operational condition is achieved by rotating the rotor about a rotational axis, with various embodiments specifying the degree of rotation required for this transition.

Furthermore, the patent details additional features such as a gasket for sealing, different configurations for the retention ring and rotor engagement, and the use of a porous solid support within the fluid channel of the rotor. The method outlined in the patent for rotating the rotary valve from a storage condition involves disengaging the retention ring from the rotor through relative motion between the rotor and stator, reducing the spacing between the rotor valving face and stator face, and sealing the apertures to the stator ports. Additional steps include aligning the gasket with the apertures and stator ports, positioning the rotary valve for pneumatic source alignment, and utilizing fluid channels within the gasket for fluid flow. Overall, the patent presents a comprehensive design and method for efficiently transitioning a rotary valve from storage to operational condition, highlighting the innovative features and functionalities incorporated into the design.
