摘要： PROBLEM TO BE SOLVED: To provide a hydraulic control device for a working machine allowing an operator to change a set value for difference in pressure of a flow rate control valve freely, based on the system for ensuring the fixed flow rate of actuator with the flow rate control valve with pressure compensation function.
SOLUTION: A circuit configuration constituted by connecting a plurality of hydraulic actuators used as an oil pressure source in common with a hydraulic pump in parallel and operating and controlling with the control valves, respectively, includes the flow rate control valve 30 with the pressure compensation function for controlling the flow rate to keep difference in pressure between before and after a pressure oil supply opening in a control valve 29 for crushing to a set value. The flow rate control valve 30 is constituted to allow the set value for the difference in pressure to be changed through pilot pressure when operating the control valve 29 for crushing. On the other hand, a pilot pressure control valve 41 for changing control pressure by orders from the controller 40 based on the operation of a means 39 for ordering set value for difference in pressure is provided to allow the operator to freely change the set value for the difference in pressure of the flow rate control valve 30 with the pilot pressure control valve 41.

摘要： PROBLEM TO BE SOLVED: To secure a circuit flow rate required to a high load pressure actuator during composite operation, achieve to improve energy efficiency, and simplify valve configuration.
SOLUTION: A hydraulic control device is configured so as to provide a priority valve 30, which is a pressure compensated flow control valve, in a discharge line 29 of a hydraulic pump 27 to supply a priority flow secured by the priority valve 30 through the first passage 31 to a crushing cylinder 12 and at the same time to supply a surplus non-priority flow through the second passages 33, 34, 15a to a swivel motor 10 which is the second priority actuator and an arm cylinder 7 when operating the crushing cylinder 12 which is the first priority actuator predefined among a plurality of hydraulic actuators. Besides, it is configured so as to supply the priority flow through the third passages 34, 15b to the swivel motor 10 and supply the surplus non-priority flow to the arm cylinder 7 when there is no crushing operation but swivel operation.
