ABSTRACT:
A motor-compressor unit comprising a vibration motor (1) having a single-part magnetizable stator (2) in the form of a W, arcuate air gaps (9, 10) being formed between the peripheral surface (6) of the central limb 3 of the W and each of the outer limbs (4, 5) of the W, and an armature (11) which is reciprocatingly pivotable about a motor shaft (12). The armature comprises at least one permanent magnet pole element (13), at least one coil (16, 17) arranged on the stator, an alternating current through the coil producing an oscillating movement of the armature (11), a compressor (21) having a linearly reciprocating piston (24) which is coupled to the armature (11), the coupling (25) being arranged diametrically opposite the pole element (13) relative to the motor shaft (12).
