Abstract:
A relay valve based accelerated brake pipe application and release system, said application and release system comprising:(a) an electronic control module; (b) a source of fluid pressure; (c) a valve means connected to said source of fluid pressure for receiving and transmitting fluid pressure signals, said valve means having a fluid connection to an exhaust to atmosphere; (d) an accelerator volume having a predetermined volume and having a fluid connection to said valve means for storing said predetermined volume of fluid; (e) a brake pipe transducer electronically connected to said control module and having a fluid connection to said valve means for transmitting a first pressure signal to said control module; (f) a cut-out solenoid valve electronically connected to said control module and having a fluid connection to said brake pipe transducer for receiving at least one of a cut-in and a cut-out signal; (g) an emergency solenoid valve electronically connected to said control module and having a fluid connection to said cut-out solenoid valve for receiving an emergency signal; (h) a cut-out means having a fluid connection to said emergency solenoid valve for opening and closing a fluid connection; (i) an application solenoid valve electronically connected to said control module and having a fluid connection to said cut-out solenoid valve for receiving an apply signal and transmitting a pilot pressure to said cut-out solenoid valve; (j) a release solenoid valve electronically connected to said control module and a including a fluid connection to said cut-out means for receiving a release signal and transmitting a pilot pressure to said application solenoid; and (k) a control transducer electronically connected to said control module and including a fluid connection to said release solenoid valve for transmitting a second pressure signal to said control module.
