Abstract: A linear compressor according to an embodiment of the present invention comprises: a shell; a cylinder which is provided inside the shell and forms a compression space of a refrigerant; a frame which is coupled to the outer side of the cylinder; a piston which is provided so as to perform a reciprocating movement in an axial direction inside the cylinder; a motor which supplies power to the piston; and a spring mechanism which is coupled to the piston to allow the piston to perform a resonant movement, wherein the spring mechanism may comprise: a support which is connected to the piston and comprises a spring support unit having one or more insertion holes formed therein; a first coupling protrusion which extends from the rear side of the spring support unit along the edge of the insertion hole; a support cap which is inserted into the insertion hole and comprises a second coupling protrusion protruding from the front side of the spring support unit; a first resonant spring which is inserted into the outer circumferential surface of the second coupling protrusion; and a second resonant spring which is inserted into the outer circumferential surface of the first coupling protrusion.

Abstract: 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.
