FIELD: machine building.
SUBSTANCE: invention discloses a working valve part of a brake distribution valve comprising a housing with a set of holes and a main piston assembly, which comprises working step valve and working slide valve. Stepped valve has a first side, in which a set of holes is made. Working slide consists of a seat of a stepped valve with a set of holes in the first side of the spool and a slide valve with a set of holes in the opposite side of the spool second side. Sets of holes in first side of working stepped valve, in seat of stepped valve and in working slide valve are intended for performance of accelerated action valve function.
EFFECT: technical result is provision of accelerated reaction of brake cylinder during operations related to operation of brakes, higher overall braking power of train and possibility of more effective stopping of longer and heavier freight trains.
