    摘要: An independent flow rate controlling hydraulic system for pressure control of an excavator, in which a hydraulic system of the excavator can be variably controlled via independent flow rate control. The hydraulic system includes a plurality of actuators which actuate a working apparatus, a pressure control-type hydraulic pump which feeds working fluid to the actuator, first and second electronic proportional control valves which are disposed at a piston-side inlet flow path and a load-side inlet flow path connected from the hydraulic pump to the actuators, third and fourth electronic proportional control valves which are disposed at a piston-side outlet flow path and a load-side outlet flow path connected from the actuators to a hydraulic tank, and a control unit which variably controls areas of the flow paths by controlling the first, second, third and fourth electronic proportional control valves depending on an amount by which a control stick is manipulated.

    摘要: A hydraulic system control unit, a hydraulic system and a working machine for controlling a hydraulic system adapted to perform at least one hydraulic work function in a working machine are provided. The hydraulic system performs the hydraulic control function in accordance with an operation signal determined by a hydraulic system control unit. In a first step the control unit receives an operator control input associated to the work function. In a second step the control unit receives a load input indicative of a load associated to the work function. Moreover, in a third step the control unit determines the operation signal in response to the operator control input and the load input.
