摘要

PURPOSE: An oil feed apparatus for compressor of refrigerator is provided to prevent abrasion of each component arranged within the compressor by feeding sufficient amount of oil even during the low speed operation of the compressor. CONSTITUTION: An oil feed apparatus comprises a cylindrical piece(131) fixed to the bottom of a crank shaft(110), which rotates along with the rotation of the crank shaft; a propeller(132) installed within the cylindrical piece, which allows an oil to rise by the relative motion with the cylindrical piece; and a rotation preventing unit fixed at the bottom of the propeller, which prevents rotation of the propeller. The rotation preventing unit includes an elastic member(133) having an end fixed to the bottom of the propeller, and a rotation preventing portion(141) for preventing rotation of the elastic member.
