ABSTRACT:
The disclosure of this invention includes a pressure swing adsorption oxygen concentrator having a plurality of zeolitic molecular sieve beds. The pressure and air flow in each bed is alternately charged between pressurizing and air flow in one direction to bleeding and counter flow in the opposite direction. Each time this change occurs, additional oxygen enriched gas from the pressurized bed to increase the incremental oxygen purity. These changes in this invention are initiated by a pressure sensitive transducer which detects a predetermined upper pressure limit. The air compressor drive includes a spring-biased swash plate which reciprocates the piston rods of reciprocating piston compressor pumps.
