Abstract
In an anti-skid pneumatic braking system for vehicles a brake is applied by air from a first reservoir and the braking effort modulated by air from a second reservoir. The brake is connected to the second reservoir through two normally closed diaphragm valves in series, the first valve opened by air supplied to the brake from the first reservoir when the brake is applied and the second valve opened by air supplied from the second reservoir in skid conditions. Additionally a third normally closed diaphragm valve can be connected across the diaphragm of the brake actuator and is opened in skid conditions.
