TRAIN BRAKING CYLINDER PRESSURE CONTROL SYSTEM AND RAILWAY TRAIN Russian patent published in 2019 - IPC B60T13/66 B60T15/36 

FIELD: machine building.

SUBSTANCE: group of inventions relates to the railway transport. Train braking cylinder pressure control system comprises load feedback device, train brake air reservoir, distribution valve, two-way valve and relay valve. Load pressure feedback device is configured to generate load pressure based on train load conditions. Brake air reservoir of train is configured to provide braking air reservoir pressure. Distributing valve is configured to adjust brake air reservoir pressure and train brake pressure and to output preliminary control pressure of indirect braking. Two-way valve is configured to select and output the larger of two preliminary control pressures. Relay valve is configured to control several input pressures and to output final pressure of brake cylinder.

EFFECT: possibility to stop the train with the same deceleration and identical braking in the conditions of the same speed, but different loads, thus facilitating control of the signal system and providing safety and comfort when driving.
