Abstract

Disclosed is an oil supply apparatus for a hermetic compressor including an oil feeder mounted at a bottom end of a crank shaft rotated by a driving unit, for sucking oil, an oil passage formed inside the crank shaft, for guiding the oil sucked by the oil feeder, and an oil injection hole formed on a sleeve inserted onto an eccentric unit formed at the top end of the crank shaft, for injecting the oil sucked into the oil passage into a cylinder for compressing fluid. The oil supply apparatus for the hermetic compressor improves efficiency of the compressor by efficiently cooling the cylinder by sufficiently supplying the oil stored at the lower portion of the casing to the cylinder.

Description

technical field [0001] The present invention relates to an oil supply device for a hermetic compressor, and more particularly, to such an oil supply device for a hermetic compressor which improves compression mainly by cooling the cylinder by supplying oil to the cylinder machine efficiency. Background technique [0002] In general, different compressors can be used according to different compression methods. Hermetic reciprocating compressors are mainly used in air conditioning units that require small size and light weight. [0003] figure 1 A cross-sectional view of a conventional hermetic compressor is shown. [0004] A conventional hermetic compressor includes: a housing 104 with a sealed space, which is connected with a suction pipe 102 and a discharge pipe (not shown), and stores oil 106 in its lower part; a drive unit 108 arranged at the lower part of the housing 104 for to generate rotational force; the compression unit arranged on the upper part of the casing 1...
