ABSTRACT:
A hydraulic braking system is provided in which the speed of increase of the hydraulic pressure to the wheel cylinders is controlled so that appropriate braking force is ensured while at the same type preventing the road wheels from being positioned in a lock-up condition. In order to provide for such an operation, the locking condition of the road wheels may be detected during braking operation and the anti-lock control system operated so that changeover valves are positioned by a control system so that output pressure of a hydraulic booster is applied to the anti-lock control valves and to the flow control valves so as to appropriately changeover between one of two operating positions in response to the locking condition of the road wheel. In order to provide for such fluid communication of the braking system, a multi-stage orifice arrangement is provided in connection with the anti-lock control valves and the flow control valves.
