ABSTRACT:
A rapid cycle pressure swing adsorption oxygen concentration method uses a mechanical valve that has at least one cam-actuated flow control valve to switch flow of fluid, such as compressed air coming into a sieve tank that is fitted with molecular sieve materials. The cam-actuated flow control valve is repeatedly actuated by the rotating cams to become open or closed to complete a cycle that precisely controls the flow direction, pressure conditions and pressurized timing in the sieve tank whereby performance and efficiency of producing rapidly oxygen is high.
