Apparatus for generating oxygen by the pressure swing method includes a plurality of grouped vessels each having a molecular sieve bed, a first port of each vessel providing oxygen-enriched effluent from the bed and a second port permitting alternate pressurization and purging of the bed. A novel rotary control valve includes a housing around which the vessels are grouped, having an operating shaft driven by a constant speed rotor. First and second chambers within the housing spaced along the shaft have respective pressure and purge valve control rotors ...
For use in a system for oxygen generation including a plurality of vessels each containing a molecular sieve bed and each having a first port for providing an oxygen-enriched effluent from the bed and a second port for alternate pressurizing and purging of the bed, rotary control valve apparatus comprising a valve housing, a shaft rotatably journalled in said housing and adapted for being driven for rotation, said housing providing first and second chambers spaced along the length of said shaft, respective pressure and purge control valve rotors carried ...
