Abstract

브레이크 액압 제어장치는 매스터 실린더로부터 휠 브레이크로 연장된 메인 유체통로에 제공되고 배출밸브를 구비한 휠 브레이크 액압 제어밸브를 가진다.
배출유체 저장기가 제공되어 배출밸브로부터 배출된 브레이크 액을 일시적으로 저장한다. 펌프가 제공되어 브레이크 액을 배출유체 저장기 밖으로 뽑아 내어 메인유체통로로 돌려보낸다. 유체공급통로는 펌프로부터의 흐름복귀점의 상류점에서 메인유체통로로부터 분기하여 배출유체 저장기로 연장된다.
트랙션제어 전환밸브가 제공되어 트랙션제어중에 매스터 실린더쪽의 흐름복귀점으로부터 유체흐름을 체크한다. 셧오프밸브는 배출유체 저장기내의 브레이크 액량이 소정레벨을 초과한다면 배출유체 저장기쪽의 유체공굽통로로부터 유체흐름을 체크하는 행정반응형 체크밸브이다.
