Rotary valve with rotor, stator, and fluid tight seal
A rotary valve, as described in the granted patent US11920700B2, comprises a rotor with apertures, a stator with stator ports, and a retention element with a retention ring and biasing element. The valve transitions from a storage condition to an operational condition through relative motion between the rotor and stator, creating a fluid-tight arrangement. The retention ring's engagement with the rotor maintains the storage condition, which is released by their relative movement, allowing the rotor to freely rotate when in an operational state. The valve includes a gasket for sealing, and various configurations of retention rings and rotor shapes to facilitate the transition between storage and operational conditions.
The method outlined in the patent involves rotating the rotary valve from a storage condition by disengaging the retention ring from the rotor through relative motion between the rotor and stator. This action reduces the spacing between the rotor valving face and stator face, sealing the apertures to the stator ports. The method also includes aligning the valve with a fluid channel containing a porous solid support and positioning it for pneumatic source alignment. Additionally, the method involves aligning a gasket with the apertures and stator ports before sealing, ensuring proper fluid flow. Overall, the patented rotary valve and its associated method provide a mechanism for efficient fluid control with a seamless transition between storage and operational states, enhancing its practical applications in various industries.
