Abstract
A spring support structure for reciprocating compressor having a frame unit elastically supported inside a closed container; a reciprocating motor fixed at the frame unit; a compression unit having a piston combined to an armature of the reciprocating motor and a cylinder to be fixed at the frame unit; and a spring unit supporting a spring support provided at the armature or the piston and guiding a reciprocal movement of the piston. The spring unit includes a plurality of front springs supporting one side of the spring support in parallel and a plurality of the rear springs supporting the other side of the spring support. Because the front and rear springs elastically supporting both the armature and the piston are arranged in parallel to overlap with each other for a certain range, the horizontal length of the spring is reduced, resulting in a compact compressor.
