摘要： Provided is a reciprocating compressor. The reciprocating compressor includes a cylinder having a compression space, a piston inserted into the cylinder to define the compression space while being reciprocated, the piston having a suction passage to communicate with the compression space, a gas bearing having a bearing hole passing through the cylinder so that a refrigerant gas is injected between the cylinder and the piston to support the piston with respect to the cylinder, and a flow resistance part disposed on one side of the cylinder to restrict a flow of the refrigerant gas flowing toward the bearing hole. The bearing hole comprises a guide groove recessed from the outer circumferential surface of the cylinder in a circumferential direction; and a plurality of nozzle parts extending from the guide groove toward an inner circumferential surface of the cylinder, wherein the guide groove has a cross-sectional area greater than that of the nozzle parts.

摘要： 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.

摘要： A linear compressor and a refrigerator including a linear compressor are provided. The linear compressor may include a shell coupled to a suction inlet, through which a refrigerant may be introduced, and a discharge outlet, through which the refrigerant may be discharged, a cylinder disposed within the shell to accommodate a piston reciprocated to compress the refrigerant introduced through the suction inlet, a frame that accommodates the cylinder, the frame being mounted inside the shell, and a discharge cover coupled to a front surface of the frame to discharge the refrigerant compressed by the piston to the discharge outlet. A front surface of the cylinder that faces the discharge cover may be spaced a predetermined distance from the discharged cover.
