制御回路。 A flow rate control circuit that controls the discharge flow rate of a hydraulic device that drives a travel hydraulic motor, etc., and includes a plurality of hydraulic pumps and a plurality of sequence valves, and the output side of the hydraulic pump is connected to the flow rate through the sequence valve. The system is characterized by the provision of bypass channels that communicate with the oil tank, and the multiple sequence valves are set to open and close at different preset pressures according to changes in the load pressure on the hydraulic motor side. flow rate control circuit.
