ABSTRACT:
In addition to oxygen concentrator apparatus utilizing two zeolite beds and alternating, pressure controlled pressurization and exhaust cycles, with a swash plate cylindrical pump having a pressure sensitive idle mode, improved oxygen concentrator apparatus is also disclosed. The improved oxygen concentrator apparatus has an isothermal, high volume, low pressure air flow system with unrestricted air conducting lines and ports throughout for more efficient and effective oxygen production. It includes a unique rotary vane pump designed for essentially isothermal air pumping and has precision collet mounted rotor with centering apparatus, tapered vanes for reduced wear and erosion, and combination cast iron pump chamber liner with external aluminum finned casing to enhance both durability and heat dissipation. It also includes a combination double one-way and balancer valve for controlling the flow of oxygen-enriched air downstream from the zeolite beds.
