Title:
BRAKING LIQUID PRESSURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JPS6478961
Kind Code:
A
Abstract:
PURPOSE:To provide a liquid pressure control device of an anti-lock control device for wheel and thereby enable control even immediately after dismissing of power, by supplying brake pressure to the back pressure chamber at the time of anti-locking, and returning the brake pressure to the master cylinder through pushing back of a pressure piston. CONSTITUTION:When a wheel 49 sliped, a build valve 46 and a cut valve 48 close and a supply valve 38 opens, and the brake liquid in the wheel cylinder concerned 45 is sealed with the pressure held constant, and also the brake liquid is supplied to the back pressure chamber 11 from an accumulator 35. This opens a check valve 13 to allow the pressure liquid to flow into a pressure chamber 12, and thereby a pressure piston 21 is pushed back, and the brake liquid in a pressurization chamber 23 is returned to the cylinder 31, and the brake pedal 32 is rustituted. This permits control even immediately after dismissing of power, and connecting a traction valve 41 as shown by the broken line allows also traction control.
