Abstract: A linear compressor is provided that may include a shell in which a discharge port may be provided, a cylinder disposed in the shell to define a compression space for a refrigerant, a piston disposed to be reciprocated in an axial direction within the cylinder, a discharge valve disposed on or at one side of the cylinder to selectively discharge the refrigerant compressed in the compression space, a valve spring coupled to the discharge valve to provide a restoring force, and a stopper coupled to the valve spring to restrict deformation of the valve spring. The stopper may include a guide recessed in a direction in which the valve spring is deformed to reduce an impulse between the stopper and the valve spring.

Abstract: A linear compressor is provided. The linear compressor may include a suction valve with a plurality of wings. Each of the plurality of wings may include two first edge portions that extend in an outer direction of a fixing portion, and a second edge portion forming an outer circumferential portion of the wing. A distance between a first edge portion of a first wing among the plurality of wings and a second edge portion of a second wing among the plurality of wings gradually increases toward the outer direction of the suction valve.
