<p>Rotary sequencing valve comprising a rotor (1) having a rotor face (7) rotatable about an axis (5) perpendicular to the rotor face, wherein the rotor face (7) has a plurality of openings (9,11), one or more of which are disposed at a selected radial distance from the axis, and wherein the rotor includes at least one passage (17) connecting at least one pair of the plurality of openings. The valve includes a flexible port plate (19) having a first side (23) and a second side (25), wherein the first side (23) faces the rotor (1) and engages the rotor such that the flexible port plate (19) can be rotated coaxially by the rotor (1) and can move axially with respect to the rotor, wherein the flexible port plate (19) has a plurality of ports (21,27) between the first and second sides (23,25), which ports are aligned with the openings (9,11) in the rotor face. The valve also includes a stator (37) having a stator face (35) disposed coaxially with the rotor (1) and the flexible port plate (19), wherein the second side (25) of the flexible port plate is in sealable, slidable rotary contact with the stator face (35), wherein the stator face (35) has a plurality of openings (39,41,43), some of which are disposed at the selected radial distance from the axis, and wherein the plurality of openings extend as passages (45,47,49) through the stator. The valve may be used in pressure or temperature swing adsorption systems. <IMAGE></p> |
