摘要
A freight brake control valve device in which the emergency piston slide valve is arranged to provide continuous, periodic, local reductions in the brake pipe pressure in response to initial actuation of the emergency piston when a service rate of brake pipe pressure reduction is made, in order to quickly propagate a brake pipe pressure reduction wave along the train and accordingly provide an accelerated application of the train brakes. This accelerated application function in response to a service rate of brake pipe pressure reduction is achieved concurrently with the quick action chamber "breathing" function, the latter being presently incorporated in the emergency piston slide valve to stabilize the emergency piston following initial actuation thereof, so as to prevent further actuation of the emergency piston to emergency position.
