Abstract
An improvement in pneumatic anti-skid braking systems for at least one wheel of a vehicle, of the type having a first valve system for causing a controlled reduction in braking pressure in a brake actuator upon reception of a control signal from an anti-skid control device sensitive to the dynamic state of at least one wheel of the vehicle, and a second valve system for causing a subsequent controlled rise in pressure after the signal from the anti-skid control device has been removed, the improvement being the provision of an accumulator in parallel with the first valve system and having two unidirectional valves, one at each side, which permit the accumulator to charge up to the braking pressure during normal braking, store this pressure upon anti-skid release of the braking pressure, and then deliver its charge to the circuit, causing a rapid increase of braking pressure after the anti-skid control signal is removed from the first valve system.
