ABSTRACT:
A magnetically actuated linear displacement compressor for use in an oxygen concentrator is provided, including a cylinder and a diaphragm mounted for reciprocating movement in the cylinder. The diaphragm divides the cylinder into two longitudinal portions and includes a permanent magnet and a peripheral edge that sealably engages the inside surface of the cylinder. Gas is introduced into and discharged from each of the cylinder portions. There is a linear actuator that includes a series of windings arranged along the cylinder. Successive groups of at least one of the windings are selectively energized and de-energized in a reciprocating pattern to generate a reciprocating magnetic field which drives the diaphragm reciprocally through the cylinder such that gas is alternately drawn into and discharged from one cylinder portion while the reverse sequence occurs in the other cylinder portion.
