Claims (5)

  1. 케이싱과, 상기 케이싱내에서 회전가능하게 지지되는 로우터와, 한 단부에서 상기 케이싱에 형성된 흡입개방부와, 다른 단부에서 상기 케이싱에 형성된 배출개방부로 이루어지고, 상기 압축기가 유량과 압력비에 관하여 넓은 조작범위를 갖는 스크류압축기에 있어서, 상기 배축개방부가 경사져서 절단된 노치부를 구비하여압축된 기체가 어떤 고정점에서 점차로 배출되며, 이 고정점에서 상기 로우터와 상기 케이싱에 의해 한정된 한 홈의 체적비가 홈의 맞춰 넣어진 체적비보다 작은 것을 특징으로 하는 스크류압축기.
  2. 제1항에 있어서, 상기 고정점은 ViB/ViA의 체적비가 70%-90%내에 있는 위치에서 선택되고, 여기서 ViB가 어떤 고정점에서의 체적비이고 ViA가 상기 맞춰넣어진 체적비인 것을 특징으로 하는 스크류압축기.
  3. 제1항 또는 2항에 있어서, 경사진 형상으로 절단된 노치부의 체적(V*)이 로우터와 케이싱에 의해 한정된 한 홈의 흡입체적 Vmax에 대하여 약 1%-6%로 셋트되는 것을 특징으로 하는 스크류압축기.
  4. 제1항 내지 3항중 어느 한항에 있어서, 기체가 노치부를 포함하지 않는 곳에서 배출되기 시작할때 상기 노치부의 체적(V*)이 한 홈의 체적 VA에 관하여 약 1%-8%로 셋트되는 것을 특징으로 하는 스크류압축기.
  5. 제1항 내지 4항중 어느 한 항에 있어서, 노치부의 체적(V*)은 기체가 노치부를 통하여 점차로 배출되기 시작하는 점 B와 기체가 노치부를 포함하지 않는 곳에서 배출되기 시작하는 점 A사이에서 한 홈의 체적의 양에서의 감소에 관하여 약 5%-50%로 셋트되는 것을 특징으로 하는 스크류 압축기.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
