Abstract: A linear compressor is provided. The linear compressor may include a cylinder that defines a compression space, a piston having a plurality of suction holes through which a refrigerant is introduced into the compression space, and a muffler connected to the piston and through which the refrigerant supplied to the piston flows. The muffler may include a seat seated on one side of the piston, and a protrusion arranged inside the piston. The protrusion may include plurality of flow pipes that extends from the seat to an inside of the piston to guide the refrigerant to the plurality of suction holes and a resonator arranged at one side of the plurality of flow pipes and having a resonance space therein.

Abstract: A linear compressor is provided that may include a cylinder, to which a discharge valve may be coupled; a first piston, which may be provided to enable a reciprocating motion in an inside of the cylinder; a second piston, which may be provided to enable a reciprocating motion in an inside of the first piston; a first compression chamber formed between the discharge valve and the first piston; and a second compression chamber formed between the first piston and the second piston. The first piston and second piston may move in opposite directions with respect to each other.
