An air distributor of brake of railroad transport vehicles contains a housing with a main piston located in it and made with two disks in the form one whole with a valve, which forms with the housing a main chamber and a chamber of spare tank. In the valve an external neck is made which is connected with a channel with an axial turning, in which a spring-loaded supply valve is located, which interacts with a equalizing piston spring-loaded in loading modes by means of supports. The air distributor also contains a chamber of additional discharging of main, a brake chamber, an accelerator of emergency braking and an accelerator of brake release made in the form of mobile partitions, which form with the housing chambers connected with supply and discharge channels. For guaranteeing equalizing brake release throughout the entire length of train in the equalizing piston a central through annular groove is made and an asymmetrical longitudinal channel connected by means of in-series made channels with the central through annular groove connected by channels with the brake chamber, the brake cylinder and with atmosphere. In the central through annular groove a plunger is located which is rigidly connected with the spring-loaded supply valve. |
