Abstract
There is provided a linear compressor, which can reduce parts production costs and simplify a part installation process by decreasing the number of main springs. The linear compressor comprises: a cylinder providing a space for compressing a refrigerant; a piston linearly reciprocating inside the cylinder to compress the refrigerant; an inner stator; an outer stator; a permanent magnet connected to the piston and linearly reciprocating between the inner stator and the outer stator; a supporter piston connected to the piston, at least part thereof being extended in a radial direction of the piston; a plurality of front main springs positioned on the same axis as the piston, one ends of which being supported by the supporter piston; and one rear main spring positioned on the opposite side of the piston, one end of which being supported by the supporter piston.
