본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제2도는 일단이 폐쇄되고 소정의 암로터(1)의 윤곽에 해당하는 윤곽을 지닌 내부벽을 병합한 모울드(20)를 개략적으로 도시한다.

Claims (5)

  1. 각각 나선형 랜드(3, 5)와 홈(4, 6)을 지니는 숫로터(2)와 암로터(1)의 적어도 두개의 로터를 구비하며, 그중 적어도 하나의 로터가 거의 플라스틱 재료로 되며 바람직한 것은 금속축 즉 코어상에 형성된 탄성유체의 압축 또는 팽창을 위한 스크루우형 회전기계에 있어서, 상기 하나의 로터가 25000N/㎜2이하 의 탄성계수를 지니는 플라스틱재료로부터 사출성형되는 암로터(1)이며, 작업유체의 의해 가해진 압력의 결과로서가 아니라 플라스틱 재료의 경화 즉 응고 및 온도변화에 의해 발생되는 칫수변형의 결과로서 랜드(3)가 다른 로터(2)와의 충돌의 경우에 탄성적으로 변형될수 있도록 상기 플라스틱의 탄성계수에 적합한 두께를 암로터(1)의 랜드(3)가 지니 것을 특징으로 하는 스크루우형 회전기계.
  2. 제1항에 있어서, 플라스틱 재료가 10000N/㎜2(이하의 탄성계수를 지니는 폴리머인 것을 특징으로 하는 스크루우형 회전기계.
  3. 제1항 또는 제2항에 있어서, 플라스틱 재료가 극히 짧은 섬유와 같은 적당한 재료로 보강된 열경화성 수진인 것을 특징으로 하는 스크루우형 회전기계.
  4. 제1항 내지 제3항중 어느 한항에 있어서, 축(8)즉 코어가 로터랜드(3)의 바닥속으로 연장되고, 로터랜드(3)의 평균두께와 거의 같은 거리를 통하여 로터표면(4)으로부터 간격진 오목표면(11)에 의해 연결되는 나선형랜드(10)를 구비한 것을 특징으로 하는 스크루우형 회전기계.
  5. 제1항 내지 제4항중 어느 한항에 있어서, 플라스틱 재료의 탄상계수는, 몇백분의 1밀리미터 정도로 암로터(1)의 윤곽에 있어서의 국부적인 돌기가 다른 로터(2)와 충돌할 때 탄성적으로 평면해지도록 하기에 적합한 것인 것을 특징으로 하는 스크루우형 회전기계.
