Abstract

Disclosed herein is a linear compressor in which a piston reciprocally moves in a cylinder upon receiving a reciprocating drive force of a linear motor to compress working-fluid, for example, refrigerant, received in the cylinder. The linear compressor comprises the piston adapted to reciprocally move in the cylinder, the piston being internally formed with a suction path, a suction valve to open or close the suction path of the piston to selectively connect the suction path of the piston to the interior of the cylinder, and a suction valve stopper to limit the degree of opening of the suction valve, whereby no excessive stress is applied to the suction valve. This has the effect of eliminating damage and deformation of the suction valve, minimizing vibration and noise due to the opening/closing operations of the suction valve, and maintaining the compression efficiency of the compressor at a constant value.
