Document Type and Number:
Japanese Patent JP2022001769
Kind Code:
A
Abstract:
To provide a hydraulic drive system which can suppress an influence exerted to the responsiveness of a hydraulic actuator caused by the impartment of a variation of a regeneration flow rate.SOLUTION: A hydraulic drive system 1 comprises: a hydraulic pump 11 for supplying a working fluid to a hydraulic actuator 2; a meter-in control valve 12 for controlling a flow rate of the working fluid flowing to the hydraulic actuator from a hydraulic pump; a meter-out control valve 13 for controlling a flow rate of the working fluid discharged from the hydraulic actuator into a tank; and a regeneration valve 14 for supplying the working fluid discharged from the hydraulic actuator to the hydraulic actuator. The meter-out control valve is connected to the hydraulic actuator in parallel with the regeneration valve.SELECTED DRAWING: Figure 1
