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.
