Abstract
The invention provides a hydraulic regeneration device which can reduce the pressure loss of a passage, increase the energy recovery efficiency, and reliably prevent the malfunction of a power generator or use-side equipment using the generated power. The interruption or drop in the function of the device is prevented even in the case of malfunction of the power generator or the use-side equipment using the generated power. An intermediate pressure passage connecting a plurality of first release valves, second release valves and solenoid switch valves of a main element is straight-line shaped, and an intermediate pressure passage of the main element and an auxiliary element is straight-line shaped. Therefore, the number of bends or intersections in the passage is reduced, and the energy recovery efficiency is improved. When the torque of the power generator cannot be adjusted, the solenoid switch valve is closed, and the oil supply for a hydraulic motor is stopped, such that the oil is discharged to an oil tank through the second release valve, and the hydraulic motor is stopped.
