Abstract

내연기관용 배기가스 터보과급기는 상호 공축상에 배열된 터빈 및 원심 압축기로써 본질적으로 구성된다. 날개(11) 형성된 확산기는 터빈에 의해 구동된 압축기 임펠레와 인접한다. 외부 압축공기원(5)으로부터 주입되는 보조공기 구동부는 압축기 부재에 설치된다. 보조공기 구동부는 바람직하게는, 유동방향으로, 보조공기를 확산기 입구(10)의 영역내로 도입시키는 다수의 이첵터(9)를 가진다.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1 도는 디젤엔진상의 압축공기 공급부를 구비한, 배기 가스 터보 과급기의 회로를 나타낸 개략도.
제 2 도는 배기가스 터보과급기의 압축기 부재의 부분 단면도.
제 3 도는 압축기 부재의 부분 정면도.

Claims (5)

  1. 공축상에 배열된 터빈 및 원심압축기를 기본적으로 구비하며, 날개가 형성되어 있는 확산기는 터빈에 의해 구동되는 압축기 임펠러와 인접하고 또한 외부 압축 공기 공급원으로부터 공급되는 보조공기의 구동부가 압축기 부재에 설치되는 내연기관용 배기가스 터보과급기에 있어서, 보조공기 구동부는 보조공기를 확신기 입구의 영역내로 도입시키는 다수의 이젝터를 갖는 것을 특징으로 하는 배기가스 터보과급기.
  2. 제 1 항에 있어서, 보조공기가 유동방향에서 확산기 입구로 도입되는 것을 특징으로 하는 배기가스 터보과급기.
  3. 제 2 항에 있어서, 보조공기가 각각의 두 인접한 확산기 날개 사이에 도입되는 것을 특징으로 하는 배기가스 터보과급기.
  4. 제 1 항에 있어서, 다수의 이젝터가 압축기 케이싱내에 배열된 공통의 메인링에 설치되는 것을 특징으로 하는 배기 가스 터보과급기.
  5. 보조공기의 공급은 내연기관이 아이들링상태에 있을 때 확산기입구가 수용할 수 있는 전량을 유임시키는 방식으로 제어되며, 보조공기량은 압축기 임필러의 중가하는 가속도에 따라서 상승적으로 교축되며, 또한 보조공기의 공급은 공칭 회전속력에 도달할 때 차단되는 것을 특징으로 하는 배기가스 터보가급기.
