Description

부압배력 장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 의한 부압배력 장치를 브레이크 배력장치에 적용한 일실시예를 표시한 종단면도, 제2도는 이 배력장치에 사용되는 제어밸브의 스프링을 지지하는 리테이너와 입력축과의 분해 사시도.

Claims (1)

  1. 프론트셸(2)과 리어셸(3)에 의해서 형성된 공간내에 대하여 진퇴자재케 배설되고, 상기 리어셸(3)을 기밀히 또한 슬라이드 자재케 관통하는 밸브보디(4)와, 이 밸브보디(4)에 연결됨과 동시에, 상기 공간내를 부압이 도입되는 정압실(9)과 작동시 대기압의 공기가 도입되는 변압실(10)로 구획하는 파워피스톤과, 상기 밸브보디(4)에 슬라이드 자재케 배설된 밸브 플런저(17)와, 이 블브 플런저(17)에 연결되고, 상기 밸브보디(4)내에 진퇴자재케 배설된 입력축(18)과, 상기 밸브보디(4)내에 설치되고, 상기 밸브플런저(17)에 의해서 작동되어서 상기 변압실(10)을 대기 또는 상기 정압실(9)에 선택적으로 연통시키도록 바꾸어서 제어하는 제어밸브(22)를 적어도 구비한 부압배력장치에 있어서, 상기 밸브플런저(17)와 상기 입력축(18)은 단일부품에 의해 일체로 형성되어 있음과 동시에, 상기 밸브플런저(17)의 상기 밸브보디(4)내에 대한 안내부(17a)의 축방향길이는, 작동시에 입력축(18)이 최대로 기울때의 각도를 허용할 수 있는 크기로 설정되고, 또한 상기 제어밸브(22)의 스프링(23)(23)을 지지하는 리테이너(27)가 상기 밸브보디(4)의 대기 도입구측에서 착탈가능하게 상기 입력축(18)에 결합되어 있는 것을 특징으로 하는 부압배력장치.
