hydraulic braking systems for vehicles antiblockier -.

摘要

In an anti-lock braking system incorporating a solenoid-operated fluid flow control valve (11), the rate at which fluid can normally be dumped to release a brake (1) is increased by the provision of a pilot valve (31). The pilot valve (31) is adapted to open by a pressure drop across a diaphragm (32). The pressure drop is established when an exhaust valve (22,24) opens upon energisation of the solenoid (15) in response to an anti-lock signal.
