Abstract
A linear compressor is provided. The linear compressor includes a cylinder having a refrigerant compression space inside; a piston, linearly reciprocating inside the cylinder to compress a refrigerant; a frame having the cylinder affixed at one end and a mounting groove at a lower portion; an oil feed assembly positioned in the mounting groove to supply oil; an oil supply path in a linear shape, positioned at a lower portion inside the frame to communicate with the mounting groove and with a bottom of the cylinder and which supplies oil between the cylinder and the piston; and an oil recovery path in a linear shape positioned at an upper portion inside the frame to communicate with an upper side of the frame and with a top of the cylinder and which recovers the oil between the cylinder and the piston.
