Abstract

본 발명은 실린더 내측에서 축방향으로 왕복 직선 운동하는 피스톤과, 피스톤과 반대방향으로 왕복 직선 운동하는 디스플레이서를 포함하고, 실린더와 피스톤과 디스플레이서 사이에 가변하는 압축공간을 형성하는 극저온 냉동기에 있어서, 피스톤에 제공되어 압축공간으로부터 유동하는 냉매를 저장하는 저장홈; 압축공간과 저장홈을 연통시키도록 피스톤의 축방향으로 형성된 유로; 유로를 개폐시켜 압축공간으로부터 저장홈으로 냉매의 흡입을 조절하는 박형의 피스톤 밸브; 그리고, 피스톤 밸브를 고정시키도록 피스톤의 축방향으로 체결된 볼트;를 포함하기 때문에 고압 상태에서도 구조적으로 피스톤 밸브를 견고하게 고정시킬 수 있고, 피스톤 밸브의 작동 신뢰성을 높일 수 있다.
