More Information
Summary:Provided is a hydraulic circuit capable of saving a pump flow rate while hydraulic fluid is being accumulated in an accumulator. The hydraulic circuit has: a couple of boom cylinders that simultaneously operate the same operation by the hydraulic oil supplied under pressure from main pumps; an accumulator in which pressure of the hydraulic oil is accumulated; a pressure accumulating circuit that accumulates the pressure of the hydraulic oil extruded from one boom cylinder in the accumulator; and a regenerating circuit that regenerates the hydraulic oil extruded from the other boom cylinder to the boom cylinders.
