FIELD: compressor engineering, in particular in lubricating and cooling systems of cooling plant hermetically sealed compressor. SUBSTANCE: hermetically sealed compressor has cylinder with inner annular boring which immediately connects upper directional oil ejection channel with intake/supplying device through longitudinal-transverse channels of electric motor shaft. Piston has annular boring which is connected with cylinder annular boring in piston dead point. EFFECT: simplified compressor structure and enhanced sealing reliability of piston couple along with piston couple effective cooling, resulting in increased cooling performance, decreased power consumption and reduced noise level. 2 dwg
