Abstract
Brakes (3, 4) on the wheels (7, 8) on a common axle are each controlled by a separate skid control unit (16, 17) each including a memory chamber (33, 34), and a single latch valve (21) common to both units closes at the first skid point to be sensed by a sensor (11, 12) on each wheel. The rate of re-application of the two brakes is controlled in response to signals from the individual sensors, but at rates of pressure increase determined by each respective memory chamber, and by flows of pressure controlled by restrictors (47).
