Abstract
PURPOSE: To improve an operation speed of an actuator, by a method wherein the actuator, switch valves, and check valves, the number of which is equal to the number of the switch valves, are combined together, and a hydraulic circuit is constituted such that pressure oil from 2 hydraulic pumps is simultaneously or individually fed to the actuator.
CONSTITUTION: Pressure oil from hydraulic pumps 1 and 2 is fed to discharge lines 20 and 21. A revolving motor 3 (a switch valve 6), travelling motors 4 and 10 (switch valves 7, 13), an arm cylinder 5 (a switch valve 8), a bucket cylinder 9 (a switch valve 12), a boom cylinder 11 (a switch valve 14), an attachment 22 (a switch valve 15) and the like are installed in the hydraulic circuit, and energizing is conducted through the operation of their respective switch valves. This hydraulic circuit obtains a desired maneuverability.
