HYDRAULIC AMPLIFIERS POSITIONONG SERVO-SYSTEM

摘要

The invention relates to a central summer servo-mechanism, used for positioning hydraulic amplifiers. According to the invention, the hydraulic amplifier positioning servo-mechanism consists of a reaction nut that tends to bring the control screw to the initial position, and of an electric engine, that moves through some guides stepping on some ballbearings, mounted on some eccentric shafts, ensured against self-loosening with some screwed pins mounted in a support; the reaction nut is connected to a reaction wheel by some conic sleeve tightened with a nut.
