초록

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 ...
