Abstract

Provided is a linear compressor. The linear compressor includes a cylinder disposed in a shell to define a compression space for a refrigerant, a piston installed to reciprocate in the cylinder, a motor assembly that allows the piston to move in an axial direction of the cylinder and thereby to compress the refrigerant introduced into the compression space, a nozzle which is provided in the cylinder and through which a portion of the refrigerant introduced into the compression space passes, and a cylinder filter installed in the cylinder and disposed at an inlet-side of the nozzle. At least one or more surfaces of the cylinder filter are oil-repellent coated.
