Abstract: A linear compressor and a refrigerator including a linear compressor are provided. The linear compressor may include a compressor casing connected to each of a suction inlet, through which a refrigerant may be introduced, and a discharge outlet, through which the refrigerant may be discharged, a compressor body mounted within the compressor casing, within which the refrigerant suctioned in through the suction inlet may be compressed due to a linear reciprocating motion of a piston in an axial direction of the compressor casing and discharged into the discharge outlet, and at least one plate spring disposed on each end of the compressor body in the axial direction.

Abstract: A linear compressor is provided. The linear compressor may include a cylinder that defines a compression space, a piston having a plurality of suction holes through which a refrigerant is introduced into the compression space, and a muffler connected to the piston and through which the refrigerant supplied to the piston flows. The muffler may include a seat seated on one side of the piston, and a protrusion arranged inside the piston. The protrusion may include plurality of flow pipes that extends from the seat to an inside of the piston to guide the refrigerant to the plurality of suction holes and a resonator arranged at one side of the plurality of flow pipes and having a resonance space therein.

Abstract: A linear compressor, a shell for a linear compressor, and a method for manufacturing a shell of a linear compressor are provided. The shell may have at least one portion having a multilayer plate, in which at least two plates may be stacked in a direction substantially perpendicular to an axis of a piston so as to accommodate a cylinder, the piston, which may be reciprocated within the cylinder, and a motor assembly directly connected to the piston to provide a drive force to the piston. At least one resonator may be disposed in or at at least a portion of an inner surface of the shell.
