Abstract
An oil supply apparatus for a linear compressor reduces the number of valves which control oil suction and discharge, thereby enabling fabrication and assembly of an apparatus and supplying an oil of an adequate amount to friction areas of driving elements, and increases a compression force of a mass, thereby increasing circulation volume of an oil. The oil supply apparatus for the linear compressor, includes: a compressor unit in which an oil discharge outlet is formed; an oil supply pipe disposed at an outer side of the compressor unit, an end of which communicates with an end of the oil discharge outlet; an oil valve an end of which is fixedly engaged with a side portion of the compressor unit and the other end of which is selectively in contact with the other end of the oil discharge outlet; and a discharge cover positioned at an outer side of the oil valve and engaged with the compressor unit, so that an oil path is formed between the discharge cover and the compressor unit.
