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

FIELD: engines and pumps.

SUBSTANCE: amplifier incorporates the working fluid source connected, via working fluid feed differential lines with throttles, to the nozzles. A shutter one end is arranged between the said nozzles, its second end being rigidly fixed in the magnetostriction drive arm center part formed by the first and second arms with the like and identical windings connected to the like opposite-phase terminals of the control unit. Here note that the amplifier is furnished additionally with the actuator connected, by its opposite-phase outputs, to the first and second tubular nozzles in the material identical to that of the aforesaid drive with one-type windings connected to the first and second terminals of the control unit. Note that the O-like magnetostriction drive forms the second arm parallel to the first one and made up of the third and fourth arms with one-type windings connected to the first and second terminals of the control unit, respectively.

EFFECT: higher reliability.
