Abstract

본 발명은 실린더의 행정체적이 고정되어 있는 밀폐형 압축기에 있어서, 냉동능력(부하)의 변경 필요시 및 냉매의 변경시에는 기존 압축기의 실린더구조로는 냉동능력의 저하가 필연적이었으므로, 압축기 외부의 작동지시수단에 의하여 크랭크샤프트와 코넥팅로드 내측에 설치된 솔레노이드밸브를 작동시켜서 크랭크샤프트의 편심축과 피스톤의 코넥팅로드 길이를 조절하므로서 압축과정 종료후 상사점의 위치는 종래와 같도록 설계하였으며 흡입과정이 종료되는 하사점의 위치가 달라지기 때문에 실린더 행정체적이 증가하게 되므로 대체냉매 사용시나 압축기의 실린더 체적을 변경시킬 필요가 있을때 사용할 수 있는 것을 특징으로 한 대체 냉매용 압축기에 대한 것이다.According to the present invention, in the hermetic compressor in which the stroke volume of the cylinder is fixed, when the refrigerating capacity (load) needs to be changed and the refrigerant is changed, the refrigerating capacity is inevitably reduced by the cylinder structure of the existing compressor. By operating the solenoid valve installed inside the crankshaft and the connecting rod by the indicating means to adjust the eccentric shaft of the crankshaft and the connecting rod length of the piston, the position of the top dead center after the end of the compression process is designed to be the same as before. Since the position of the bottom dead center is changed, the cylinder stroke volume is increased, so it can be used when the replacement refrigerant is used or when it is necessary to change the cylinder volume of the compressor.
