Abstract
In a fluid-pressure operated braking system for vehicles operating fluid from a supply for actuating a wheel brake is supplied to the brake through a skid control unit interposed in the line between the supply and the brake, and a skid responsive device responsive to a skid signal is incorporated for operating a valve assembly to relieve the pressure of the fluid supplied to the brake at a skid point. The unit incorporates a memory chamber for controlling the rate of brake re-application following correction of a skid, and the memory chamber is charged with air only when the skid signal is received. When separate control units are provided for the brakes of wheels at opposite ends of an axle, the memory chambers are interconnected by a pneumatic connection incorporating a restrictor.
