ABSTRACT:
In an hydraulic anti-skid braking systems for vehicles, for example motor cycles or light passenger cars, a supply of operating fluid from a supply to a vehicle brake is modulated in accordance with skid signals from a skid sensing devices suitably an opto-sensor, which are electrical in nature, and an hydraulic pump incorporating at least one plunger working in a bore has a working chamber to control brake re-application following skid correction. The supply of fluid from the supply to the brake is modulated by a solenoid-operated valve assembly which is responsive to the skid signals, the valve assembly incorporating a normally-open isolating valve disposed between the source and the brake, and a normally closed dump valve disposed between the brake and a reservoir for fluid.
