Abstract
PURPOSE:To release the sudden rise in liquid pressure at the time of increasing the pressure of an AB (antiskid brake) control valve and simplify an AB control by providing a flow rate control valve for switching over to an ordinary condition and a throttled condition on the upper course side of the AB control valve in a brake pipe line and switching over to the throttled condition at the time of the AB control operation. CONSTITUTION:Braking pressure from a master cylinder 10 by means of a brake pedal 12 is fed into the wheel cylinders 20a, 20b, 21a, 21b of each wheel via pipings 16, 22, and AB control valves 18, 24 to carry out the prescribed antiskid brake control. And, flow rate control valves 48, 52 for switching over to an ordinary condition and a throttled condition are provided on the upper course sides of the AB control valves 18, 24 and, at the time of an AB control operation, solenoids 50, 54 are operated to switch over the flow rate control valves 48, 52 to a throttled condition. Thereby, sudden increase in liquid pressure can be suppressed at the time of the switchover from pressure reduction to pressure increase of the AB control valves 18, 24 while reducing the number of times of switching to pressure reduction, to simply carry out the AB control.
