Abstract

PURPOSE:To improve the reliability of action, when one system is in failure, by constituting a selector valve providing pistons having the first pair of right and left equal pressure receiving surfaces receiving antilock controlled master cylinder pressure and the second equal pressure receiving surfaces directly receiving master cylinder pressure. CONSTITUTION:This select valve has step-shaped pistons 20 inserted into right and left small bore cylinder chambers 12, 12' and central large bore cylinder chambers 13, 13' forming a cylinder chamber in a casing 11, forming the first equal pressure receiving surfaces 24, 24' by end faces of small bore parts 22, 22' of the piston 20 and the second equal pressure receiving surfaces 25, 25' by both faces of collars 23 in the center. The small bore parts 22, 22' form passages 26, 26' in the diametric direction communicating with the equal pressure receiving surfaces 24, 24' through opening and closing valves 30, 30', and a brake pressure, controlled in fluid pressure control units 2, 2', is input to these passages 26, 26' through input ports 14, 14'. While the equal pressure receiving surfaces 25, 25' are connected to each pressure chamber in a master cylinder 1 through ports 16, 16'.
