FIELD: aeronautical engineering.
SUBSTANCE: each control channel of proposed actuator unit is provided with electro-hydraulic booster, actuating cylinder whose rod is rigidly connected with rods of other channels, auxiliary correction cylinder with hydraulic coupling and correction sensor, correction valve and cut-in valve. Correction valve is made in form of sleeve with throttling orifices and spring-loaded three-bead spool valve located in sleeve. Sleeve cavities are connected with cavities of actuating mechanism and with grooves between spool valve beads by means of holes made in spool valve. Throttling orifices of sleeve are connected with cavities of auxiliary cylinder forming negative overlapping with edges of extreme beads of spool valve.
EFFECT: enhanced reliability.
