FIELD: refrigerating engineering; compressors.
SUBSTANCE: invention relates to hermetic compressor for refrigerating equipment and it can be used in lubrication system of hermetic compressors with vertical crankshaft and slotted-link mechanism. Hermetic compressor has operating cylinder with piston connected through slotted-link mechanism with crank of vertical crankshaft provided with oil feed channel. The latter communicates at one side with oil bath, and at other side with hollow body rigidly coupled with one of links of slotted-link mechanism and provided with radial holes for directed delivery of part of lubricant to piston-cylinder friction zone. Hollow body is made in form of sleeve whose cylindrical part is secured in oil feed channel, and bottom is located over end face of crank. Radial holes should be preferably arranged between end face of crank and bottom of sleeve at level of upper generatrix of piston-cylinder pair.
EFFECT: increased efficiency of cooling and lubrication of friction zones.
