Abstract

본 발명은 냉장고, 에어콘 등과 같은 냉열 장치에 있어서 증발기로부터 도입되는 냉매를 압축하는 왕복동형 압축기에 관한 것으로서, 피스톤핀이 삽입되는 피스톤의 핀내경부 하단에는 관통되지 않도록 암나사부를 형성하고, 상기 피스톤핀의 하단에는 상기 암나사부에 체결될 수 있도록 수나사부를 형성하였으며, 상기 피스톤핀의 상단에는 조립이 쉽도록 하기 위하여 +자, -자, 삼각홈, 또는 다각홈의 드라이버 삽입용 홈을 형성함으로써, 조립 생산성을 향상시키고, 종래의 로킹핀의 파손으로 인한 피스톤핀의 유동과 실린더장치내의 여러 부품의 손상 및 압축기의 작동 불능 현상을 미연에 방지할 뿐만 아니라 압축기의 신뢰성을 향상시킬 수 있는 매우 유용한 발명이다.The present invention relates to a reciprocating compressor for compressing a refrigerant introduced from an evaporator in a cooling device such as a refrigerator or an air conditioner, and includes a female screw portion so as not to penetrate the lower end of a pin inner diameter of a piston into which the piston pin is inserted. A male screw part was formed at the lower end to be fastened to the female screw part, and an upper part of the piston pin was formed with a driver inserting groove for +,-, triangular, or polygonal grooves for easy assembly. It is a very useful invention that can improve the reliability of the compressor as well as prevent the flow of the piston pin and damage of various components in the cylinder device and the malfunction of the compressor due to the breakage of the conventional locking pin.
