Abstract: An linear compressor and a linear motor for a linear compressor is provided. The linear compressor may include a shell, in which a suction inlet may be provided, a cylinder disposed in the shell to define a compression space for a refrigerant, a frame coupled to an outer side of the cylinder, a piston reciprocated in an axial direction within the cylinder, a stator cover coupled to the frame, and a linear motor supported by the frame and the stator cover to provide power to the piston. The stator cover may include a body, and at least one frame coupling portion coupled to the frame. The at least one frame coupling portion may extend from the body toward the frame.

Abstract: 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.

Abstract: A linear compressor and a refrigerator including 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, at least one nozzle disposed in the cylinder to introduce at least a portion of the refrigerant discharged through the discharge valve into the cylinder, and at least one filter provided in the shell. The at least one filter may be disposed in a refrigerant passage defined from the suction inlet to the at least one nozzle via the discharge valve. Foreign substances or oil contained in the refrigerant introduced into the at least one nozzle may be filtered while passing through the at least one filter.
