Abstract
A pressure swing adsorption oxygen generator to separate oxygen from air for use with a pressure source generating a high pressure and a low pressure. The pressure swing adsorption oxygen generator includes an adsorption bed having a bed of nitrogen absorbent material; and a multi-position rotary valve for controlling pressure swing adsorption of the adsorption bed, and being couplable to the pressure source for fluid communication therewith and in fluid communication with the adsorption bed. The rotary valve includes a cam having first and second rotary positions, in the first rotary position of the cam the rotary valve communicating high pressure generated by the pressure source to the adsorption bed and in the second rotary position of the cam the rotary valve communicating low pressure generated by the pressure source to the adsorption bed.
