Abstract
임펠러(3)의 임펠러 날개(2)에 내구적으로 부착된 링(1)과 회전대칭 홈 형태로 압축기의 케이싱(4)내에 요홈(5)을 구비한 압축기의 특성 선도를 확장시키는 안정화 장치에 있어서, 상기 링(1)은 임펠러(3)의 입구 영역에 국한되고, 임펠러의 회전시, 링이 요홈(5)내에서 움직일 수 있으며, 거기서 링(1)과 케이싱(4)의 벽 사이에, 단지 종래의 미세간극이 존재하는 방식으로 입구영역에 부착된 상기 수단에 의해 고압측에서 저압측으로 갭 흐름의 형성이 방지되어, 압축기의 효율증가를 가져오고 압축기 특성이 확대되는 결과를 가져온다. 아울러 날개상의 진동부하가 감소된다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
