ELECTRIC AIR DISTRIBUTOR OF THE BRAKE OF A RAILWAY VEHICLE Russian patent published in 2018 - IPC B60T13/68 

FIELD: machine building.

SUBSTANCE: invention relates to the field of mechanical engineering, and more particularly to electric air distributors of brakes of railway transport. Electric air distributor of the brake of the railway vehicle, controlled by the operator by means of the brake control unit of the train, comprises an electric unit, a pneumatic relay and a brake release unit. Electrical unit contains electromagnetic valves. Exhaust solenoid valve is equipped with an additional electromagnetic coil. Brake release unit contains an electromagnetic relay with normally closed contacts, an AC frequency divider and a pneumoelectric relay with a camera and an electric switch. Chamber is divided by a spring-loaded movable partition, one part of the chamber is pneumatically connected to the atmosphere, and the other part to the control pressure chamber. Coil of the electromagnetic relay is connected to the brake control unit of the train, to the main coil of the discharge valve and the brake valve coil. Contact of the electromagnetic relay is connected to the brake control unit of the train and through the frequency divider of the alternating current and the electric switch of the pneumo-electric relay to the additional electromagnetic coil of the tempering solenoid valve.

EFFECT: electric air distributor of the brake of a railway vehicle is proposed.
