Abstract

마스타 실린더 저장소에서 브레이크유체가 마찰제어동안에 브레이크회로내로 흡입될지라도 브레이크 시스템의 마스타 실린더가 손상되지 않는 장치가 구비된다. 휠 브레이크 압력밸브는 메인라인에 구비되어 있다. 또한 이 시스템은 제어밸브로부터 방출된 유체를 저장하기 위한 방출된 유체저장소와 방출된 유체저장소에서의 유체를 메인라인의 유체복귀지점내로 복귀시키기 위한 펌프와 유체복귀지점으로부터 마스타 실린더쪽으로 어떤 유체흐름을 체크하기 위한 마찰제어 전환밸브와 메인라인으로부터 분기된 공급라인에 구비되고 통상 브레이크동안 메인라인과 연통하도록 채택된 중간 유체저장소를 또한 포함하고 있다. 이 시스템은 마찰제어동안에 공급라인으로부터 중간저장소쪽으로 어떤 유체흐름을 체크하도록 메인라인으로 부터 분기된 연결라인에 구비되어 있는 걸리간 밸브를 갖추고 있다. 다른 전환밸브가 구비되어 중간저장소와 방출된 유체저장소와의 사이에서 연통을 개폐한다.
