Abstract
A linear compressor may include a shell, a cylinder provided in the shell to define a compression space for a refrigerant, a frame to fix the cylinder to the shell, a piston reciprocated within the cylinder, a discharge valve disposed on or at one side of the cylinder, a discharge cover coupled to the frame and having at least one chamber to reduce pulsation of the refrigerant discharged through the discharge valve, and a valve spring disposed on the discharge cover to provide a restoring force to the discharge valve. The discharge cover may include a cover body having a discharge hole, through which the refrigerant discharged through the discharge valve may be discharged outside of the discharge cover, and a guide passage defined in the cover body to guide at least a portion of the refrigerant discharged through the discharge valve into the at least one chamber.
