DEVICE FOR CONTROLLING SINGLE-LINE CIRCUIT OF ELECTROPNEUMATIC TRAIN BRAKE Russian patent published in 1994 - IPC

FIELD: railway transport. SUBSTANCE: the function of control wire is executed by line conductor. Suspension of end hose is provided with a capacitor. To protect against interferences from generators, the circuit of direct current generator has choke coil, whereas the circuit of alternate cycle generator has a capacitor. The line conductor is laid inside a polyethylene pipe. To reduce resistances in direct and alternate cycle circuits, the electropneumatic brake has two working positions. In the position for longer train length the capacitor and choke coil are shunted in generator circuits. EFFECT: enhanced efficiency in operation. 2 dwg
