Linear compressor having suction muffler

A linear compressor comprising:

• a shell comprising a refrigerant suction part configured to suction refrigerant;
• a cylinder located in the shell;
• a piston configured to reciprocate within the cylinder, the piston comprising a piston body that defines a first inner space therein and a piston flange;
• and
• a suction muffler through which suctioned refrigerant passes, the suction muffler comprising:
• a first muffler disposed in the first inner space of the piston body, and
• a second muffler that contacts the first muffler, the second muffler protruding toward an outside of the piston body and defining a second inner space therein,
• wherein the first muffler comprises:
• a first muffler body that defines a refrigerant passage and that extends in an axial direction, and
• a first muffler flange that extends from the first muffler body in a radial direction, that is coupled to the piston flange, and that defines a flange communication hole configured to provide the refrigerant in the first inner space in the piston body to the second inner space in the second muffler, and
• wherein the first muffler flange partitions the first inner space in the piston body from the second inner space in the second muffler.
