MULTI-CHANNEL ACTUATOR Russian patent published in 2006 - IPC B64C13/36

Abstract SU 1839995 A1

FIELD: aeronautical engineering.

SUBSTANCE: proposed actuator has several control channels with electro-hydraulic amplifier, cut-in valve, auxiliary hydraulic cylinder, pressure drop correction unit, feedback sensor and main hydraulic cylinder whose piston is rigidly connected with pistons of similar actuating cylinders of other sub-channels. Each sub-channel is provided with spool valve hydraulically connecting the cavities of auxiliary hydraulic cylinder with respective cavities of main hydraulic cylinder at arising of design pressure in its cavities.

EFFECT: improved static and dynamic characteristics.
