Abstract
A compressor comprises a reciprocating motor disposed within a casing, for generating a driving force; a compressing unit for sucking, compressing and discharging gas by a linearly reciprocating motion of a piston connected to the reciprocating motor; a plurality of resonant springs connected to the piston, for inducing a resonant motion to the linearly reciprocating motion of the piston, wherein centers of the resonant springs are positioned at the same radius on the basis of a central axis of the piston.
