Abstract: A motor-driven compressor particularly for a refrigerator has a cylinder-and-piston unit whose piston is driven from a shaft of a rotor of an electric motor, two sound-damping chambers communicating with a cylinder of the cylinder-and-piston unit, and a bearing element mounted on a stator of the electric motor and having a portion forming a main bearing for the shaft of the rotor, a relatively small bridge-like portion overlapping only a part of a winding of the electric motor, and two legs located diametrically opposite one another and mounted on the stator of the electric motor. The sound-damping chambers may be of one piece with a cover of the cylinder and the latter may be a separate member without the cover.
