본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1a도는 본 발명의 원리를 설명하는 개략도
제1도는 브레이크 동작을 개시하기 위하여 브레이크에의 적용을 대기하는 위치의 가동 밸브를 지니는, 본 발명에 따라 제공된 제동 장치의 개략 단면도
제2도는 브레이크 페달의 이동에 응답하여 공기 제동 압력이 수요될 때를 가정하여 중간 위치의 밸브를 보여주는 개략도

Claims (6)

  1. 작동기에 대한 제동압력을 조절하는 주 밸브와 미리 설정된 역치를 넘는 제동압력에 응답하여 단속적왕복운동을 개시시키는 역치수단 사이의 챔버에서 왕복운동하는 서틀피스톤(shuttle piston), 제동압력을 작동기에 작용시키는 챔버로 부터의 공기 라인, 셔틀피스톤이 왕복운동할때 작동기에 단속적인 온/오프 제동충격을 발생하도록 셔틀피스톤의 왕복운동에 응답하여 챔버의 압력을 보지하고 배출하는 밸브, 상기 챔버에 제동공기압력을 발생시키는 수단, 2개의 격실의 같은 크기의 공기압력에 응답하여 셔틀피스톤이 한 방향으로 이동하도록 각기 단부마다 다른 크기의 면적으로 지지하는 셔틀피스톤의 양측 단부의 격실, 상기 한 방향으로의 셔틀밸브의 이동에 의한 충격시 상기 챔버로 공기 제동압력을 보내도록 주 밸브를 작동시키는 수단, 배출밸브가 닫힌 안정 위치로 셔틀피스톤의 양단부에 대한 공기압력에 응답하여 반대방향으로 셔틀피스톤을 복귀시키는 수단, 제동압력이 상기 역치를 넘을 때 배출밸브의 개방으로 상기 역치수단에 의해 주 밸브를 향해 셔틀피스톤을 안정위치로 부터 멀어지게 밀치는 수단등을 포함하는 것을 특징으로 하는, 차량의 제동작동기를 제어하도록 브레이크 페달에 의해 조절되는 공기 제동압력으로부터 동작가능한 차량의 단속적 제동장치.
  2. 제1항에 있어서, 제동압력의 크기에 따라 셔틀피스톤 왕복운동의 횟수를 제어하는 수단을 특징으로 하는 차량의 단속적 제동장치.
  3. 제1항에 있어서, 제동압력을 받아 편향력을 극복하도록 탄력있게 바이어스된 피스톤을 포함하는 역치수단을 특징으로 하는 차량의 단속적 제동장치.
  4. 제1항에 있어서, 대기와 통하는 배출구 통로를 개폐하도록 플렌지를 구비한 피스톤 몸체를 통하여 슬라이드가능한 로드를 포함하는 셔틀피스톤을 특징으로 하는 차량의 단속적 제동장치.
  5. 제1항에 있어서, 챔버로의제동 공기압력 통로를 개방하도록 셔틀피스톤의 충격에 의해 이동가능하며 그에 의해 챔버의 제동압력으로 스프링 바이어스에 대항하여 밀쳐지며 상기 챔버로 부터의 제동 공기압력을 차단하도록 스프링 바이어스되는 이동가능한 주 밸브부재를 특징으로 하는 차량의 단속적 제동장치.
  6. 제1항에 있어서, 중심축을 따라 함께 연결되어 원통형 몸체를 형성하는 다수의 부분들로된 하우징 조립체를 특징으로 하는 차량의 단속적 제동장치.
