Relay valve based accelerated brake pipe application and release system

摘要

A relay valve based accelerated brake pipe application and release system having an electronic control module. A source of fluid pressure is connected to a valve device for receiving and transmitting fluid pressure signals. The valve device is connected to an exhaust to atmosphere. An accelerator volume has a fluid connection to the valve device for storing a predetermined volume of fluid. A brake pipe transducer is electronically connected to the control module and has a fluid connection to the valve device for transmitting a first pressure signal to the control module. A cut-out solenoid valve is electronically connected to the control module and includes a fluid connection to the brake pipe transducer for receiving at least one of a cut-in and a cut-out signal. An emergency solenoid valve is electronically connected to the control module and has a fluid connection to the cut-out solenoid valve for receiving an emergency signal. A cut-out device is included for opening and closing a fluid connection and it has a fluid connection to the emergency solenoid valve. An application solenoid valve is electronically connected to the control module and has a fluid connection to the cut-out solenoid valve for receiving an apply signal and for transmitting a pilot pressure to the cut-out solenoid valve. A release solenoid valve is electronically connected to the control module and has a fluid connection to the cut-out device for receiving a release signal.
