COIL SPRING AND RECIPROCATING COMPRESSOR HAVING THE SAME

摘要

A coil spring in accordance with the present invention includes inner coils (30) formed as a wire is wound plural times; and an inflection portion (41) having a nonlinear shape and formed at an outer circumferential surface of the end coil (40), which is positioned toward the inner coil (30). When connected to other component and is constricted and relaxed to absorb an impact or a vibration transmitted from the outside, the coil spring minimizes friction generated between itself and other components so that reliability of a reciprocating compressor having the coil spring can be improved.
