Abstract

A linear compressor is provided. The linear compressor may include a shell including a suction inlet, a cylinder provided in the shell to define a compression space for a refrigerant, a piston reciprocated in an axial direction within the cylinder, a discharge valve provided at one side of the cylinder to selectively discharge the refrigerant compressed in the compression space, and at least one nozzle, through which at least a portion of the refrigerant discharged through the discharge valve may flow, the at least one nozzle being disposed in the cylinder. The at least one nozzle may include an inlet, through which the refrigerant may be introduced, and an outlet having a diameter less than a diameter of the inlet.
