METHOD OF OPERATING ELECTRO PNEUMATIC BRAKE CONTROL UNIT Russian patent published in 2010 - IPC B60T7/00 

FIELD: transport.

SUBSTANCE: electro pneumatic brake control unit comprises additional automatic braking device of the train, electric circuit components, electrically-driven air control valves, control instruments, switch assembly and traffic identifier. Traffic identifier comprises code relay of overlap conditions and braking or their electronic counterparts and sealing-off duplicator diode. Linear conductors of the front connection hose are connected via switch assembly contacts with input circuits of the code relay of overlap conditions and braking or their electronic counterparts and sealing-off duplicator diode of traffic identifier. Linear conductors of the rear connection hose are connected are connected to appropriate output terminals of the control unit. Output circuits of code relay of overlap conditions and braking or their electronic counterparts and sealing-off duplicator diode of traffic identifier are connected to appropriate input terminals of the control unit.

EFFECT: guaranteed operation of electrically-driven air control valves in heavy train and ruling out spontaneous unlocking of front connection hose with isolated suspension.
