Abstract

공조장치에 장비되는 냉매의 팽창 밸브에서의 냉매중에 혼입하는 기포에 의한 소음의 발생을 저감한다.
공조장치에 장착되는 팽창 밸브는, 밸브본체에, 수용용기에서 보내지는 액냉매의 통로와, 기화기(8)를 통과한 기상냉매의 통로를 가지고 있다. 냉매통로는 밸브실을 가지고 있으며, 밸브좌에 맞닿아지는 부재에 의하여 냉매의 통과량이 제어된다. 밸브부재는, 기상냉매의 온도를 압력에 응해서 축방향으로 이동하는 밸부부재 구동봉에 의하여 작동한다. 액냉매의 입구포트와 밸브실 사이에 오리피스를 구비하고, 죄는 구멍에 의하여 냉매중의 기포의 밸브실로의 침입을 갑소한다. 밸브실에서 밸브좌까지의 통로에도 테아퍼를 달아, 기포가 찌부러지는 것을 방지한다.
선택도 제1도

Description

Claims (2)

  1. 감압해야할 액냉매의 통로와, 증발기에서 압축기로 향하는 기상냉매의 통로가 있는 밸브 본체와, 액냉매의 도로중에 설치되는 밸브좌 및 밸브실과, 일단부가 밸브 본체에 장치되는 다이어프램에 고정되며, 타단부가 밸브부재를 지지하는 밸부부재 구동봉과를 가지고 있으며, 기상냉매의 온도와 압력에 대응하여 액냉매의 통로의 단면적을 조정하는 팽창밸브에 있어서, 밸브 본체의 액냉매의 입구포트와 밸브실과를 연통하는 통로내에 죄는 구멍을 가진 오리피스를 구비하는 것을 특징으로 하는 팽창밸브.
  2. 제1항에 있어서, 밸브실에서 밸브좌로 통하는 액냉매의 통로를 그 단면적이 서서히 감하는 테이퍼 벽면으로 형성하는 것을 특징으로 하는 팽창 밸브.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
