Abstract
PURPOSE: To obtain preferential control of a part of three actuators, slow speed control of all three and high speed drive of a part of the three by the speed of the three actuators with the plural number of pump, flow control valve and pressure compensation valve.
CONSTITUTION: Pressure compensation is preferentially made to a control valve 12 by connecting the primary port 15 of a preferential type pressure compensation valve 11 to the first pump 1 and also connecting the first flow control valve 12 to a reducing port 17 of the compensation valve 11. The second flow control valve 13 is subsequently connected to a bypass port 19 of the compensation valve 11 through a bypass type pressure compensation valve 14. Further, the third, the fourth flow control valves 62, 63 are connected to the second pump 5 through a bypass type pressure compensation valve 61 to effect pressure compensation while a control valve 63 is geared to control valves 12, or 13 to set a flow-out timing of a fluid from the control valve 63 later than that of the control valves 12, or 13. Furthermore, load lines 84, 85 of the control valves 63 are connected to load lines 51W54 of the control valves 12, 13 in order to effect confluence of a fluid ejected from pumps 1, 5 and supply of the fluid to an actuator 3 or 5.
