Abstract
Natural frequencies of a front side support spring and a rear side support spring of a reciprocating compressor are formed to be different such that a natural frequency of one support spring is lower than an operating frequency and a natural frequency of the other support spring is higher than the operating frequency. Both support springs may resonate in mutually opposite directions to form an antiphase, and thus, compressor vibrations may be effectively reduced without reducing a stiffness of both support springs.
