FIELD: machine building.
SUBSTANCE: hydraulic system includes feed source with constant supply pumps, main and additional overflow valves, electrohydraulic amplifiers, hydraulic cylinders, pressure and drain main lines, pressure sensor that fixes pressure rise in pressure line of pressure source and performs signal supply through automatic control system to additional valve with proportional control, which allows implementing the change in flow passage as per the specified sequence.
EFFECT: excluding the possibility of formation of hydraulic impact and pressure pulsations in hydraulic system.
