FIELD: machine building.
SUBSTANCE: proposed booster comprises adding operating amplifier with two inputs, electronic power amplifier, electromechanical converter, hydraulic control valve articulated with feedback electric transducer moving element. The latter is hydraulically communicated with delivery and rain lines and has two output lines for connection with using equipment. It comprises also matching hardware with its input connected with signal winding of hydraulic control valve feedback electric transducer. It comprises pressure difference hydroelectric transducer communicated by two hydraulic lines with hydraulic control valve output lines. Besides it includes computer with one input connected to hydraulic control valve feedback electric transducer matching hardware and another input connected with pressure difference hydroelectric transducer electric output. Output of said computer is connected with second input of adding operating amplifier.
EFFECT: higher efficiency.
