Abstract
FIELD: hydraulics. SUBSTANCE: actuator comprises hydraulic cylinder 1 with spring-loaded piston 2, output rod 3, hydraulic gate 4, connecting pipe 5 for supplying fluid to chamber 6 above the piston, and connecting pipe 7 for discharging fluid from chamber 8 to tank 9. The fluid is supplied to chamber 6 through connecting pipe 5 and pipe line 12 from tank 9 through pipe line 11 by gear pump 10. The gear pump is actuated by electric motor 13 the speed of rotation and direction of rotation of which is governed by controller 14. A control signal is fed to controller 14 from comparator 15 that compares signal from controller 16 and signal from the pickup of position of rod 17. EFFECT: enhanced reliability.
