摘要
A railway air brake pipe pressure gradient reduction arrangement, wherein pressure gradients along the pipe indicative of a brake pipe pressure fall activate a valve arrangement to temporarily vent the pipe and so speed the brake applying pressure reduction. A further valve arrangement is included for inhibiting venting when a pressure gradient is present due to a pressure rise.
