Hydraulic circuit for working machine, comprising accumulator
The present invention relates to a hydraulic circuit for a working machine, the hydraulic circuit comprising a hydraulic actuator and an accumulator for accumulating hydraulic energy discharged from the hydraulic actuator, and addresses the problem of configuring the hydraulic circuit so that high-temperature hydraulic oil does not flow into the accumulator. A means for solving the problem is to configure the hydraulic circuit in such a manner that piping (12) for cooling which has a volume corresponding to the pressure accumulation volume of the accumulator (10) is provided in an accumulator outlet/inlet oil passage (9) serving as the inlet oil passage for hydraulic oil flowing into the accumulator (10), and in such a manner that hydraulic oil cooled by the piping (12) for cooling is accumulated in the accumulator (10).
