DIGITALLY-CONTROLLED HYDROELECTRIC POWER AMPLIFIER Russian patent published in 2016 - IPC F15B3/00 F15B9/07 F15B13/43 

FIELD: hydro automatics.

SUBSTANCE: invention relates to hydro automatics, particularly to electro-hydraulic amplifiers, and can be used in high-precision control systems of working mechanisms of movable vehicles and aircrafts. Electromechanical converter is made in the form of a stepper motor with discrete nature of movement and digital control, mechanism for returning a four-clamp cylindrical slide valve in neutral position comprises a preliminarily compressed centering springs located in the end cavities of the four-clamp cylindrical slide valve.

EFFECT: obtaining a digital control and reduced impact effect of reverse jets in the hydraulic amplifier due to a stepper motor with finite number of stable positions.
