Abstract
A piston support structure for a reciprocating compressor is provided that includes a piston receiving a linear reciprocating driving power generated by a reciprocating motor. The piston is in a compression space formed in a cylinder and a first resonant spring and a second resonant spring are positioned on both sides of the piston. The first resonant spring and the second resonant spring elastically support the linear reciprocating motion of the piston. The spring constant of the second resonant spring opposite to the first resonant spring is larger than the spring constant of the first resonant spring positioned on the side of the compression space of the cylinder. Accordingly, the stress concentration of the second resonant springs for elastically supporting the piston is reduced. Accordingly, it is possible to prevent the fatigue of the second resonant springs and to extend the durability of the resonant springs.
