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

FIELD: physics.

SUBSTANCE: amplifier contains working fluid source, two working fluid supply lines, two throttles, differential nozzles, actuator, magnetostriction drive consisting of four arms, lath with gate in the middle, four one-type windings and control unit. As forming antiphased current signals and injecting them to proper windings, gate of lever magnetostriction drive is diametrically shifted, operating pressure is changed in nozzle chambers thus regulating it under preset principle within required shift range.

EFFECT: extended range of transformation and technical use area.
