Title:
ROTARY VALVE
Document Type and Number:
Japanese Patent JP2023169312
Kind Code:
A
Abstract:
To provide a rotary valve which eases requirements on a gasket elastomer sealing a surface, further increases the pressure rating, and extends operating and storage lifetimes.SOLUTION: A rotary valve 00 includes a rotor 10 and a stator 50, biased toward one another to form a fluid tight seal. The rotor comprises an integrated flow channel containing a porous solid support 45. In many cases, an interface between the rotor and the stator is made fluid-tight using a gasket. The rotary valve includes a displaceable spacer to prevent the gasket from sealing at least one of the rotor and stator. When the spacer is displaced, the gasket seals the rotor and stator together in a fluid-tight manner.SELECTED DRAWING: Figure 1A
