Improvements in hydraulically-operated anti-skid braking systems for vehicles.

摘要

An hydraulically-operated anti-skid braking system includes a pump (3) rotatable with a wheel to be braked and of the type which, once a predetermined minimum wheel speed is attained, produces a constant output flow irrespective of any further increase in the wheel speed, and a fixed orifice (40) through which the output flow from the pump (3) is circulated to provide a back pressure which is utilised to control the application of a brake. Since the pump (3) is rotatable with a wheel to be braked by the brake, the wheel is automatically prevented for locking.
