Linear compressor

A linear compressor, comprising:

• a cylinder having a refrigerant compression space inside;
• a piston that linearly reciprocates inside the cylinder to compress a refrigerant;
• a frame, to which one end of the cylinder is fixed and which has a mounting groove at a lower portion thereof;
• an oil feed assembly settled in the mounting groove of the frame, that pumps and supplies oil;
• an oil supply path in a linear shape, which is positioned at a lower portion inside the frame to communicate with the mounting groove of the frame and with a bottom of the cylinder and which supplies the oil between the cylinder and the piston;
• and
• an oil recovery path in a linear shape, which is positioned at an upper portion inside the frame asymmetrical to the oil supply path 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 piston, wherein the oil supply path is greater in diameter than the oil recovery path.
