A linear compressor is provided that may include a casing, a compressor body accommodated in the casing and defining a compression space for a refrigerant, a suction pipe coupled to a first side of the casing to supply the refrigerant to the compression space, a discharge pipe coupled to a second side of the casing to discharge the refrigerant compressed in the compression space outside of the casing, a process pipe coupled to the second side of the casing spaced apart from the discharge pipe to inject a refrigerant for supplement into the casing, and a separator that separates a mixed fluid of a refrigerant and oil injected through the process pipe.

Linear compressor

A linear compressor and a method for manufacturing a linear compressor are provided. A piston of a linear compressor may include a surface treatment body made of aluminum or an aluminum alloy; a first surface treatment provided on an outer surface of the surface treatment body by a first vacuum deposition process; and a second surface treatment provided on an outer surface of the first surface treatment by a second vacuum deposition process.

Linear compressor and method for manufacturing a linear compressor

A linear compressor includes: a shell; a cylinder provided inside the shell; a frame coupled to an outer side of the cylinder; a piston configured to reciprocate in an axial direction; a motor that supplies power to the piston; and a spring mechanism coupled to the piston. The spring mechanism includes: a support connected to the piston and including a spring support unit having one or more insertion holes; a first coupling protrusion that extends from the rear side of the spring support unit along the edge of the insertion hole; a support cap inserted into the insertion hole and including a second coupling protrusion protruding from the front side of the spring support unit; a first resonant spring inserted into the outer circumferential surface of the second coupling protrusion; and a second resonant spring inserted into the outer circumferential surface of the first coupling protrusion.
