LINEAR COMPRESSOR

摘要

A linear compressor comprises: a stationary member including a cylinder (200) for providing a space for compressing a refrigerant; a movable member linearly reciprocating with respect to the stationary member, and including a piston (300) for compressing the refrigerant inside the cylinder (200) and a supporter piston (320) connected to the piston (300) and having a support portion extended in a radial direction of the piston (300); a plurality of front main springs (320) positioned so as to be symmetrical with the center of the piston (300) and the supporter piston (320), one ends of which being supported by the front surface of the support portion of the supporter piston and the other ends of which being supported by the stationary member; one rear main spring (840) positioned at the opposite side of the piston (300), one end of which being supported by the supporter piston (320); and a back cover (560) having a support portion for constraining the other end of the rear main spring (840) from moving in a transverse direction.
