Beschreibung
Zusammenfassung:	FIELD: fluid-pressure actuators. ^ SUBSTANCE: system of hydraulic valves comprises first actuating connection and the second actuating connection which are connected with the hydraulic consumer, system of supplying connections that has the connection with the pressure source and connection with the vessel, first valve system that disconnect the system from the pressure source or controllably connect it with the first actuating connection or the second actuating connection, second system of valves that disconnects the system from the vessel or connects it controllably with the first actuating connection or the second actuating connection, and control unit that controls the first valve system and second valve system. At least one valve system is provided with the pickup of the extent of opening connected with the control unit that controls the valve system depending on the signal from the pickup of the extent of opening and reference signal. ^ EFFECT: enhanced precision of control. ^ 15 cl, 3 dwg
