Claims (2)

  1. 흡입부와 토출부를 가지고 구동부에 의해 회전되는 실린더와; 이 실린더내에 편심한 상태에 위치해 일부 외주면이 실린더의 내주면과 접해서 실린더에 대해 상대 운동을 행하는 원주형상의 피스톤과; 이 피스톤의 외주면에 형성되어 상기 실린더의 흡입부측으로 부터 토출부측에 향해서 서서히 작아지는 피치의 나사형상의 홈과; 이 홈에 출입 자유롭게 끼워 맞춰져 상기 실린더의 내주면과 피스톤의 외주면과의 사이를 복수의 작동실에 구획하는 나선형상의 블래이드를 가지는 유체 압축기에 있어서, 적어도 실린더의 흡입부측에 위치하는 상기 블래이드의 바깥지름을 상기 실린더의 안지름보다도 크게 한것을 특징으로 하는 유체 압축기.
  2. 제1항에 있어서 상기 실린더의 흡입부측에 위치하는 상기 블래이드의 바깥지름의 실린더의 토출부측에 위치하는 바깥지름보다도 크게 한것을 특징으로 하는 유체 압축기.
