HERMETIC TYPE COMPRESSOR AND REFRIGERATOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hermetic type compressor which prevents bearing damage and loss increase of a radial bearing of a crank shaft, and to provide a refrigerator in which the compressor is mounted.SOLUTION: A hermetic type compressor includes: a closed vessel where a lubrication oil is accumulated; a crank shaft which has a lower part communication hole for supplying the lubrication oil at a lower journal part; and a radial bearing which pivotally supports the crank shaft. The crank shaft includes a spiral groove which rotates from the lower journal part in a first direction. The crank shaft or the radial bearing includes a fine oil supply groove which extends from an area near the lower communication hole in a second direction away from the spiral groove.
