Abstract
A compressor includes a piston disposed in a housing and configured to be reciprocatably driven in the housing by an electromagnetic drive. A conventional linear motor drive assembly reciprocatably drives the piston in an embodiment. A magnetically-geared drive assembly reciprocatably drives the piston in another embodiment. A solenoid drive assembly reciprocatably drives the piston in another embodiment. A control system is coupled to the drive for varying piston displacement, and an accumulator conserves force by decelerating a translating assembly at the end of one stroke and accelerating the assembly in a subsequent stroke.
