The air distributor is a component of the pneumatic braking system of railway transport, which provides regulation of the supply and exhaust of air to the brake cylinders of cars. Its main function is automatic control of braking and releasing the brakes when the pressure in the line changes. When the pressure in the line increases, the air distributor releases air, releasing the brakes, and when it decreases, it supplies it to the brake cylinders, activating the braking. This ensures safe and synchronous braking of cars in the train
