<p>The present invention relates to a linear compressor (100); and more particularly, to a linear compressor (100) provided with three mainsprings (820,840) having a resonance frequency synchronized with an operating frequency, where the resonance frequency can be adjusted without varying initial positions of mainsprings (820,840) although an additional mass member (1000) may be added. The linear compressor (100) comprises: a fixed member, which includes a cylinder (200) for providing a refrigerant compression space; a movable member, which includes a piston (300) for compressing refrigerant inside the cylinder (200), a center portion that coincides with the center of the piston (300), and a support extended in a radial direction of the piston (300), and which makes a linear reciprocating motion about the fixed member; a plurality of front mainsprings (820), each of which has one end being supported on a front side of the support of the supporter (320) and the other end being supported on the fixed member, and which are located symmetrically about the center of the piston (300); a single rear mainspring (840) which has one end being supported on a rear side of the supporter (320) and the other end being supported on the fixed member; and a plurality of mass members (1000) coupled to a rear side of the supporter (320), having a predetermined distance from the outer diameter of the rear mainspring (840).</p> |
