FIELD: railway vehicles.
SUBSTANCE: distribution valve of a brake system for a railway vehicle includes a case, in which a channel for communicating with a brake line, made with the possibility of communicating via fluid with the brake line, a channel for communicating with a tank, made with the possibility of communicating via fluid with a tank, and a channel under initial pressure, made with the possibility of communicating via fluid with an initial pressure source, are formed. The distribution valve of the brake system includes a service valve of accelerated release having a valve element with the first position, in which the channel for communicating with the brake line is isolated from the channel for communicating with the tank, and the second position, in which the channel for communicating with the brake line communicates via fluid with the channel for communicating with the tank. The valve element is made with the possibility of supplying pressure from the channel for communicating with the tank to the channel for communicating with the brake line during brake release, while the valve element is driven between the first and the second positions under the pressure in the channel under initial pressure.
EFFECT: providing the possibility of faster re-charging of the train brake line, reducing the release time after the service braking, and guaranteeing the reliable brake release in cargo cars located at the back of the train.
