Abstract
A skid control device for pneumatic brake systems embodying relay valves. In response to an impending skidding condition, the control pressure on the relay valve is dumped to relieve the brake pressure. When the brakes are dumped, a latch valve isolates the operator controlled treadle valve from the relay valve and establishes an alternative actuating path for subsequent brake actuation. A regulator is interposed in this path and provides controlled pressure for subsequent re-applications during a given braking cycle. The regulator is operatively connected with a memory volume to provide a regulated pressure that is related to the pressure that existed at the time the brakes were initially dumped.
