Abstract

냉동 사이클 시스템에 짜넣는 팽창밸브의 밸브구에 발생하는 부식의 방지를 도모한다.
팽창밸브는 밸브본체(10)에 설치되는 오리피스(30)와 밸브체(9)를 보유하며, 밸브체(9)는 가동체(18)와 일체로 부착된다. 다이어프램(4)의 위동은, 부재(16)를 개재해서 작동봉(17)에 전달되며, 작동봉(17)은 가동체(18)를 작동시켜서 밸브체(9)와 오리피스(30)의 사이의 유로의 열림도를 제어한다. 오리피스(30)에 고착되는 오리피스 부재(100)는, 밸브본체(10)에 비하여 경도 높은 재료로 만들어지며, 냉매에 의하여 밸브구부에 발생하는 부식 등의 손상을 방지한다.
