Abstract: A linear compressor is provided. The linear compressor may include a suction valve with a plurality of wings. Each of the plurality of wings may include two first edge portions that extend in an outer direction of a fixing portion, and a second edge portion forming an outer circumferential portion of the wing. A distance between a first edge portion of a first wing among the plurality of wings and a second edge portion of a second wing among the plurality of wings gradually increases toward the outer direction of the suction valve.

Abstract: A reciprocating compressor including a shell, a suction pipe, a driver located at the inner portion of the shell to generate a rotary force, a compressor located in the shell and a muffler assembly is provided. The compressor includes a connecting rod configured to convert the rotary force to a linear driving force, a piston connected to the connecting rod and a cylinder into which the piston is movably inserted is provided. The muffler assembly is configured to transfer a refrigerant suctioned through the suction pipe to the cylinder and includes a suction muffler having an inner portion and a suction hole through which a refrigerant is suctioned, an inner pipe installed at the inner portion of the suction muffler, the inner pipe having a bent portion, the inner pipe providing communication between the suction hole and the cylinder and a coupler disposed at the bent portion.
