Beschreibung
Zusammenfassung:	FIELD: hydraulic drives. SUBSTANCE: invention is designed for use in power hydraulic servo systems with remote controlled adjustable pump. Proposed pump contains control and zero setting mechanisms made integral with slave cylinders connected to hydraulic actuator amplifier. The latter is coupled through hydraulic supply line with auxiliary pump. Electromechanical converter designed to control hydraulic actuator amplifier is connected to electric control circuit. Hydraulic load release automatic device includes distributor and control electromagnetic providing change-over of hydraulic supply lines of hydraulic actuator amplifier and pressure lines of auxiliary pump and lines of slave cylinders. Electromechanical converter is excited by integral power source. Control electromagnetic is connected to supply system of electric control circuit. Permanent magnets can be used as internal power source. Electromechanical converter is made in form of electromagnetic with rotary armature. EFFECT: improved reliability of protection of hydraulic servo systems with controllable pump in case of interruption of power supply at noncontrollable transient processes, provision of quick unloading of pump. 1 dwg
