A distributor valve system for a railway vehicle including 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. The relay valve has a plurality of positions corresponding to different amounts of pressurized air applied to the brake cylinder. The relay valve may include a plurality of chambers that are filled with pressurized air according to the amount of air pressure needed for the brake cylinder. A change-over device may be configured to switch the relay valve between the different positions, wherein the change-over device may be in line between the auxiliary reservoir and the relay valve. A railway vehicle may be in fluid communication with the distributor valve system via the brake pipe. |
