Abstract
A linear compressor is provided that includes a stationary member including a cylinder that provides a space to compress a refrigerant; a movable member that linearly reciprocates with respect to the stationary member, and that includes a piston that compresses the refrigerant inside the cylinder and a supporter piston having a support portion that extends in a radial direction of the piston; front main springs positioned so as to be symmetrical with respect to centers of the piston and the supporter piston, one ends of which are supported by a front surface of the support portion of the supporter piston and the other ends of which are supported by the stationary member; a rear main spring, one end of which is supported by a back surface of the supporter piston; a suction muffler that provides a passage to introduce the refrigerant while reciprocating with the movable member, reduces noise, and includes an extended part that extends toward the supporter piston; and a spring guide fixed to the supporter piston to support one end of the rear main spring on the front surface. A recessed part having a size sufficient to accommodate the extended part of the suction muffler is formed on …
