Abstract:
1. A linear compressor, comprising: 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; a plurality of front main springs positioned so as to be symmetrical with respect to centers of the piston and the supporter piston, one end of each of which is supported by a first surface of the support portion of the supporter piston and the other end of each of which is supported by the stationary member; a rear main spring, one end of which is supported by a second surface of the supporter piston; a suction muffler that provides a passage to introduce a 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 that supports the one end of the rear main spring on a first surface of the spring guide, wherein a recessed part having a size sufficient to accommodate the extended part of the suction muffler is formed on a second surface of the spring guide.
