Abstract

The present invention relates to an oil supply apparatus for a linear compressor in which elastic members are excluded, wherein oil contained in an oil supply unit is exhausted by inertia and flowed into an oil pocket which communicates with a friction portion between a cylinder and a piston in the process of which the oil supply unit reciprocates in accordance with the vibration of a compressor unit. Thus, the oil supply apparatus for the linear compressor has advantages of reducing manufacturing costs and improving the productivity. The oil supply apparatus for the linear compressor of the invention includes a compressor unit horizontally installed in a predetermined part of a hermetic vessel, and an oil supply means disposed at an outer side of the compressor unit for supplying oil contained therein to an oil pocket which communicates with a friction portion between a cylinder and a piston, which oil is exhausted by inertia due to straight reciprocation of the oil supply means in accordance with vibration of the compressor unit.
