ABSTRACT:
In a closed-type compressor with an electromagnetic reciprocating drive, reliable and stable collimation of the electromagnetic driving part with the compressive pumping part is easily established by a snug engagement of fitting seats provided in the coupling plane of the two parts and lubrication of the piston and its related part is effected by a built-in type lubrication mechanism utilizing the flow of the gas returning from the given circulation system with simplified construction as well as in the case of compressors with rotary drive, the compressor being preferably used for cooling systems.
