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.

Изобретение относится к электрогидравлическим поршневым исполнительным механизмам и может быть использовано в любой области техники. Целью изобретения является повышение надежности работы поршневого исполнительного механизма за счет устранения утечек рабочей жидкости. Поставленная цель достигается выполнением исполнительного механизма, который содержит гидроцилиндр 1 с подпружиненным поршнем 2, выходной шток 3, гидрозатвор 4, штуцер 5 для подачи рабочей жидкости в камеру 6 над поршнем и штуцер 7 для слива рабочей жидкости из камеры 8 в емкость 9. Из последней она забирается шестеренчатым насосом 10 через трубопровод II и по трубопроводу 12 подается через штуцер 5 в камеру 6. Шестеренчатый насос 10 приводится в действие электродвигателем 13, скорость и направление вращения которого задаются регулятором числа оборотов 14, управляющий сигнал на который поступает с блока сравнения 15, вырабатывающего этот сигнал на основе сравнения задающего сигнала с задатчика 16 и сигнала с датчика положения штока 17.The invention relates to electro-hydraulic piston actuators and can be used in any field of technology. The aim of the invention is to increase the reliability of the piston actuator by eliminating leakage of the working fluid. This goal is achieved by the execution of the actuator, which contains a hydraulic cylinder 1 with a spring-loaded piston 2, an output rod 3, a hydraulic lock 4, a nozzle 5 for supplying the working fluid to the chamber 6 above the piston, and a nozzle 7 for discharging the working fluid from the chamber 8 into the container 9. From the latter it is taken by gear pump 10 through line II and through line 12 is supplied through nozzle 5 to chamber 6. Gear pump 10 is driven by an electric motor 13, the speed and direction of rotation of which are set by the speed controller Otov 14, the control signal to which comes from the comparison unit 15, generating this signal based on the comparison of the reference signal from the setter 16 and the signal from the rod position sensor 17.
