Abstract

본 발명은 반제동유압제어시스템에 관한 것으로, 반제동제어가 이루어질 때에 유치는 펌프로부터 제2유입구(8)를 통해 유동제어밸브에 공급되고, 마스터실린더로부터 상기 제2유입구(8)로 한쪽방향으로만 유체가 유동되도록 상기 마스터실린더와 제2유입구(8)사이에 체크밸브(11)가 드로틀밸브(10)와 평행하게 설치되어, 팽창쳄버(12)내에 유체가 없을 때에도 체크밸브를 경유하여 마스터실린더로부터 제2유입구(8)로 유치가 연속적으로 공급되어, 제2유입구(8)에서 금속선단부의 유량조절로 인해 제1유입구(7)가 폐쇄된 상태로 유지되어 연맥동이나 펌프노이즈 및 페달진동을 효과적으로 방지해 주게 되어 있다.
