Electro-hydraulic booster has controlled element as flapper nozzle in the body. The gate rests on the pusher of the armature of electro-mechanical transformer and is directed to one of the ends of the nozzle channel of which is through throttle with constant cross-sections connected to the line of working liquid supply. The back valve has a pusher that is placed in the channel of the nozzle with possibility of displacement. The shutoff element rests on fixed seat placed at the end of the nozzle. To increase stability of pressure control the flap, the pusher and the shutoff element of the back valve are arranged as slide installed in reborings of the body, at that the flap is rigidly connected to the shutoff element of the back valve through the pusher.
