<p>PURPOSE:To provide an antiskid hydraulic pressure controller for a multicircuit brake equipment which is improved in its safety by constituting same such that a magnet valve means of a specific construction is additionally provided to an antiskid hydraulic pressure controller for a single circuit brake equipment. CONSTITUTION:A control valve 7 from which oil is not leaked out when a circuit is broken is disposed between a brake booster 2 as well as a right front wheel 8b and an antiskid actuator 4. The control valve 7 includes a hollow stepped piston 25, a plunger 28, a seat 32, balls 27, 29, a spring 33 and a magnet coil 34. Thus, during an ordinary braking operation with the antiskid operation being not effected, pressure oil from a master cylinder 2 is supplied directly to the left and right front wheels 8a and 8b, to the left rear wheel 9a through the control valve 7 and to the right rear wheel 9b through the actuator 4 to thereby effect braking operation. Meanwhile, with the antiskid operation being effective, a computer 6 responsive to a slipping phenomenon of the car changes over a change-over valve 5 to abolish the communication between an intake manifold 3 and the actuator 4. As a result, the actuator 4 operates so that the pressure of oil to be supplied to the right rear wheel 9b is decreased and the magnet coil 34 is energized to cause the control valve 7 to operate so that oil under the decreased pressure is supplied from the actuator 4 to the left rear wheel 9a.</p> |
