PROBLEM TO BE SOLVED: To provide a hydraulic pressure passage control system capable of reducing the pressure loss produced by the pressure oil discharged from an actuator for a work machine.SOLUTION: A first changeover valve 41 and a second changeover valve 42 for switching the communication state and the cut-off state between a first conduit line L12 connecting a first actuator 12 and a first direction changeover valve 14 and a second conduit line L22 connecting a second actuator 22 and a second direction changeover valve 24 are provided in a hydraulic circuit. When there is operation on the first actuator 12 and there is no operation on the second actuator 22 or in the same case, the first changeover valve 41 and the second changeover valve 42 are respectively switched from the block position to the communication position. The switching timing of the changeover valves 41 and 42 is controlled to be simultaneous or different from each other.SELECTED DRAWING: Figure 2
【課題】作業機用のアクチュエータから排出される圧油により発生する圧損の低下を図りうる油圧回路制御システムを提供する。【解決手段】第１アクチュエータ１２および第１方向切換弁１４を接続する第１管路Ｌ１２と、第２アクチュエータ２２および第２方向切換弁２４を接続する第２管路Ｌ２２との連通状態および遮断状態を切り換える第１切換弁４１および第２切換弁４２が油圧回路に設けられる。第１アクチュエータ１２に操作があり、第２アクチュエータ２２に操作がない場合またはこれと同等の場合、第１切換弁４１および第２切換弁４２のそれぞれが遮断位置から連通位置に切り替えられる。各切換弁４１、４２の当該切換タイミングが同時または相互に異なるように制御される。【選択図】図２
