US 2011/0030556 A1 · METHOD AND SYSTEM FOR GENERATING OXYGEN-ENRICHED GAS

Abstract

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.

Dependent claims

An oxygen generating system, comprising:

an oxygen generating unit including a housing having operatively disposed therein:
at least two sieve beds;
a piston disposed between, and operatively connected to the at least two sieve beds;
and
at least one magnet selectively acting on the piston;
and
a coil wrapped around an exterior surface of the housing and in operative communication with the at least one magnet, the coil being configured to drive the piston, via an electromagnetic field formed between the coil and the at least one magnet, along a length of the housing between the at least two sieve beds during at least one stage of an oxygen generating cycle for generating an oxygen-enriched gas for a user.
