DISTRIBUTION VALVE SYSTEM FOR RAIL VEHICLE AND METHOD OF BRAKING RAIL VEHICLE USING DISTRIBUTION VALVE SYSTEM Russian patent published in 2019 - IPC B60T8/18 

FIELD: machine building.

SUBSTANCE: group of inventions relates, in general, to a braking system for a rail vehicle, more specifically to a distribution valve system for a rail vehicle and a braking method using said system. Distribution valve system for a rail vehicle comprises a brake pipe; a relay valve; an auxiliary reservoir in line between the brake pipe and the relay valve to establish fluid communication between the brake pipe and the relay valve; and a brake cylinder in fluid communication with the relay valve. Relay valve has a plurality of positions corresponding to different amounts of pressurised air applied to the brake cylinder. Relay valve includes a plurality of chambers that correspond to a plurality of positions and are filled with pressurised air according to the weight of the railway vehicle. Method of braking a rail vehicle using a distribution valve system includes steps of: a) providing said distribution valve system on a rail vehicle; b) directing pressurised air from the brake pipe to the auxiliary reservoir; c) directing pressurised air from the auxiliary reservoir to the relay valve; and d) selecting the position of the relay valve, the relay valve being configured with a plurality of different positions corresponding to different amounts of compressed air, which are fed into the brake cylinder based on the weight of the rail vehicle.

EFFECT: invention enables to output a given value of brake pressure in a rail vehicle based on manual selection of the target task of brake pressure.
