FIELD: machine building.
SUBSTANCE: hydro-system consists of tank, of working equipment pump, pressure main of which is connected with rod and piston cavities of hydro-cylinder of working equipment and hydraulic motor by means of hydraulic distributors, and of safety valve. The hydro-system has an accumulator of replenishment, a hydraulic distributor, a control valve and a throttle. Also, the accumulator of replenishment is connected with a drain main, with the tank via the safety valve, with an input of the hydraulic distributor and with a control cavity of the hydraulic distributor through the control valve. Further, via a throttle, it is connected with a suction main of the pump. The suction main is coupled with an output of the hydraulic distributor.
EFFECT: reduced losses of hydraulic energy in hydraulic system.
