Linear compressor

A linear compressor, comprising:

• a fixed member including a cylinder for providing a refrigerant compression space;
• a movable member including a piston for compressing refrigerant inside the cylinder and a supporter having a center portion that coincides with a center of the piston and an extended portion that is connected to the piston and extends in a radial direction of the piston, and which performs a linear reciprocating motion about the fixed member;
• a plurality of front mainsprings symmetrically arranged about the center of the piston and the center portion of the supporter and each having a first end supported on a front side of the supporter and a second end supported on the fixed member;
• a single tear mainspring having a first end supported on the supporter, and which is positioned on a different side from the piston;
• a suction muffler which is engaged with and linearly reciprocates with the movable member to provide a passage for introducing refrigerant, and which reduces noise;
• a plurality of mass members coupled to a rear side of the supporter and being positioned a predetermined distance from an outer circumference of the rear mainspring;
• and
• a spring guider positioned between the supporter and the rear mainspring, wherein the spring guider has a plurality of cavities formed on a circumferential portion thereof.
