ABSTRACT:
A motor-compressor unit comprises a motor including a magnetizable stator; an armature oscillatable about the motor shaft axis; two coils arranged opposite each other on the stator; and a magnetizable core extending between the coils. The stator has opposed sections spaced from each other and arranged to define air gaps between such stator sections and the core at the end faces of the coils remote from each other, such air gaps being concentric about the motor shaft axis. A permanent magnet is disposed between each stator section and the core, a pole of each magnet facing the core. A plurality of pole elements is associated with the armature and is arranged such that oscillation of the armature causes one pole element to move into its respective air gap and another pole element to move out of its respective air gap. The coils and the core are arranged such that passage of an alternating current through the coils causes flux alternately to increase in a first air gap and to decrease in a second air gap and then to decrease in the first air gap and to increase in the second air gap. The compressor includes a linearly reciprocating piston, and a lever connecting such piston to the motor shaft.
