Abstract
A motor-compressor unit is provided which comprises a vibration motor (1) having an armature (3) which can perform a rotationally vibrating movement about a drive shaft (4), and a compressor (10) having at least one piston (12) which can be reciprocated in a cylinder (11) by an arm (9) of the armature (3). The couping between the piston (12) and the arm (9) comprises a sleeve (15), which is slidable in a bore (16) in the piston and which is connected to the arm (9) by a ball joint (21). The oscillating movement of the arm (9) produces a helical reciprocating movement of the piston (12). This leads to an improved lubrication.
