Abstract
The present invention relates to a reciprocating compressor in which a cylinder of a compression unit is tightly fixed to a hermetic shell, and a stator of a reciprocating motor is fixed to the hermetic shell by a support spring consisting of a leaf spring, so as to reduce the gap between a compressor body and the hermetic shell and thus reduce the size of the compressor. In addition, the masses of the members of the reciprocating motor and of the compression unit, as well as the elasticity of the spring supporting the members, are properly adjusted to offset the force being applied to the hermetic shell, thereby minimizing the vibrations of the hermetic shell. Further, the relative velocity of the reciprocating motor increases such that the relative velocity of the reciprocating motor is faster than the relative velocity of the compression unit, thereby improving the efficiency of the motor.
