A compressor is disclosed, which comprises a case, a cylinder disposed inside the case, a piston moving inside the cylinder, and a muffler provided in the piston. The muffler includes a fluid pipe provided with a resonant space formed between an outer circumferential surface and an inner circumferential surface of the piston, and a guide panel protruded from the outer circumferential surface of the fluid pipe to the inner circumferential surface of the piston and extended along an outer circumferential direction of the fluid pipe. The guide panel is provided in a plural number, and is partially opened along the outer circumferential direction of the fluid pipe to form an open area, and the open area formed in any one guide panel is covered by its adjacent guide panel.

A compressor includes a casing, a piston accommodated in a cylinder disposed inside the casing to reciprocate forward and backward, the piston being configured to define a suction space in which a refrigerant is accommodated therein, a suction muffler connected to the piston to guide the refrigerant to the suction space, a suction guide disposed behind the suction muffler and fixed to the casing, the suction guide being disposed parallel to the suction muffler in an axial direction, and a suction pipe passing through the casing to extend into the suction guide, the suction pipe being configured to suction the refrigerant. A portion of the suction muffler is disposed to overlap the suction guide in a direction crossing the axial direction.

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.

The present invention relates to a linear compressor. The linear compressor according to an aspect of the present invention includes a spring axially elastically supporting a driving assembly. The spring includes a spring body axially extending, a front spring link forming an end of the spring body by extending from a side of the spring body, and a rear spring link forming the other end of the spring body by extending from the other side of the spring body. Any one of the front spring link and the rear spring link is fixed to the driving assembly and the other one is fixed to a supporting assembly.
