METHOD AND SYSTEM FOR GENERATING OXYGEN-ENRICHED GAS

摘要

An oxygen generating system includes an oxygen generating unit including a housing having disposed therein i) at least two sieve beds, ii) a piston disposed between and operatively connected to the sieve beds, and iii) at least one magnet operatively disposed on the piston. A coil is wrapped around an exterior surface of the housing and is in operative communication with the magnet(s). The coil is configured to drive the piston along a length of the housing between the sieve beds during at least one stage of an oxygen generating cycle. The driving of the piston is accomplished via an electromagnetic field formed between the coil and the magnet(s). Also disclosed herein is a method for generating an oxygen-enriched gas using the oxygen generating system.
