Abstract

본 발명은 냉각장치의 팽창밸브에 관한 것으로, 종래와 같이 팽창기로 유입되는 냉매의 양을 조절하기 위하여 수동식 니들 밸브 또는 스탑 밸브를 팽창밸브로 사용하는 경우에는 그 조작에 불편함이 있었고, 감온센서가 구비된 자동조절 팽창밸브의 경우에는 상기 감온센서가 액관온도 검출시 외부요인의 온도변화에 대해서도 민감하게 작동하여 정확한 냉매의 유입량을 산출할 수 없다는 문제점이 있었던 바, 본 발명에서는 응축기와 팽창기를 연통시키는 냉매관 내의 압력을 측정하는 압력센서와, 그 압력센서에 의해 유통될 냉매량을 조절하도록 제어하는 유량조절 밸브로 구성함으로써, 상기 냉매의 유량조절을 수동으로 하는 불편함을 제거하고, 외부의 조건변화에도 정확한 유량조절을 가능하게 하는 효과가 있다.
