LEVER MAGNETOSTRICTION ELECTROHYDRAULIC DIRECT CONTROL AMPLIFIER Russian patent published in 2008 - IPC F15B3/00 

FIELD: physics.

SUBSTANCE: amplifier contains working fluid source, two working fluid supply lines, two throttles, magnetostriction drive with "П"-shaped arms, equivalent windings, lath and carrier, valve block and control unit. As forming antiphased current signals and injecting them to proper windings, carrier of lever magnetostriction drive is diametrically shifted, operating pressure is changed in valve block chambers thus regulating it under preset principle within required shift range.

EFFECT: higher accuracy and high-speed of conversion.
