Abstract: A linear compressor is provided that may include a shell; a compressor body accommodated in the shell to compress a refrigerant; a discharge cover assembly through which the refrigerant compressed in the compressor body may be discharged; a cover pipe that extends from the discharge cover assembly to discharge the refrigerant discharged into the discharge cover assembly to an outside of the discharge cover assembly; a discharge pipe coupled to the shell to discharge the refrigerant flowing along the cover pipe to an outside of the shell; a loop pipe having a first end connected to the cover pipe and a second end connected to the discharge pipe; and a coupling member that respectively couples both the first and second ends of the loop pipe to the cover pipe and the discharge pipe. The coupling member may include a connection member, a first portion of which is inserted into the loop pipe and a second portion of which is inserted into the discharge pipe or the cover pipe. The connection member may be formed of a steel material. At least one of the discharge pipe or the cover pipe may be formed of a steel material.

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: 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.
