Abstract
In an anti-skid braking system a brake is applied in response to the pressure of a supply of hydraulic fluid passed through a first variable orifice from a pump rotatable with rotation of a wheel to be braked so that the wheel is automatically prevented from locking. The system incorporates a second variable orifice in combination with a pre-loaded spring against which a shuttle provided with the orifice is adapted to be displaced to reduce the pressure of the supply from the pump.
