Abstract

A compressor of hermetical type in which the electric driving motor (16) is enclosed in a chamber (29), which is flowed through by the compressed medium, is driven by the driving motor via a gear drive (24, 23) enclosed in gear space (22) which is drained to an intermediate pressure in the compressor. Due to this fact the gear drive (24, 23) and adjacent bearings (6, 11, 20) are lubricated by oil of that pressure prevailing in the oil separator (31) of the compressor, whereby an oil pump can be spared.
