  • Abrasion preventive structure of reciprocating compressor
    Patent number: 7028601
    Abstract: In an abrasion preventive structure of a reciprocating compressor, by forming a coating layer made of Ni—P alloy material having high hardness onto the surface of a frame at which front (92) and rear (93) resonance springs are contacted or spring mounting grooves (91a, 92a) of a spring supporting rod (91) or spring fixation protrusions or the inner circumference of a cylinder built-in type frame, although each resonance spring (92, 93) is rotated while repeating compression/relaxation, it is possible to prevent abrasion of the spring mounting grooves (91a, 92a) or the spring fixation protrusions, and accordingly reliability of the compressor can be improved.
