Abstract
Compressor in which the moving parts such as in the driving motor, slide on one another in the absence of a lubricant and are constituted, at least in their contact zones, of polyimide having a coefficient of expansion similar to the metal parts, so as to allow the reduction of the dimensions without risk of overheating. Preferably, the polyimide is in the form of coatings and contains additives e.g. graphite, which improve the sliding. Use for small refrigerators in which the compressor and its driving motor is disposed in a hermetically closed capsule.
