Claims (3)

  1. 링형의 디퓨우저 통로를 통해 유입구로 부터 유츨스트롤로 작동유체를 이동시킬 수 있도록 회전 가능하게 장치된 임펠러를 갖는 케이싱을 구비하는 원심 압축기에 있어서, 상기 링형의 디퓨우저 통로를 형성하는 고정벽과, 상기 디퓨우저 통로내에서 상기 고정벽에 부착되는 여러개의 고정베인과 상기 여러개의 고정베인의 상승류측에 위치하여 상기 고정벽에 대해 상대적 이동이 가능하게 장치되고, 상기 고정벽에서 디퓨우저 통로를 통한 증기유동을 저지하여 이 유동상태를 최고유량 상태로 부터 완전히 억제된 유량 상태로 변화시키는 가동성의 링 수단으로 구성되는 것을 특징으로 하는 원심 압축기.
  2. 제1항에 있어서, 상기 가동성 링 수단을 상기 임펠러의 하강류에 위차하는 것을 특징으로 하는 원심 압축기.
  3. 원심 압축기의 임펠러 출구측에서 링형의 디퓨우저 통로를 통해 유동하는 유체의 유동량을 제어하는 방법에 있어서, 여러개의 안내베인을 링형의 디퓨우저 통로내의 고정위치에 고정시키는 단계와, 링형의 디퓨우저 통로를 통한 유체의 유동각이 고정베인에서의 유동각과 일치할 수 있도록 링형의 디퓨우저 통로내에 가동성링을 이동 가능하게 위치시키는 단계로 구성되는 것을 특징으로 하는 원심 압축기의 유량제어 방법.
