Merging and dividing are repeated responding to the given operation pattern. Thus, we have employed EPC valve for the solenoid valve to be used for controlling the merging and dividing valve. And in order to alleviate the shock pressure applied to the actuator in switching between the merging and dividing, the switching time has been made longer by use of EPC valve.
As explained earlier, the electronic control enables an optimum matching of the engine and hydraulic pumps, thereby realizing lower fuel costs through the total control.
Reduction of the loss by use of highly efficient hydraulic components is also aimed at.
