る制振装置の油圧駆動回路。 A hydraulic actuator that drives the load, a servo valve that controls the hydraulic pressure supplied to the actuator, a pump as a hydraulic drive source, an accumulator that accumulates hydraulic pressure from the pump, and a relief valve that regulates the pressure in the main circuit. The hydraulic drive circuit of the vibration damping device includes an electromagnetic switching valve that opens and closes the vent circuit of the relief valve, a pressure switch that detects the pressure inside the accumulator, and a pressure switch that detects the pressure inside the accumulator when it reaches the upper limit based on this detection signal. A controller is installed to stop the pump when the pressure drops to the lower limit, open the electromagnetic switching valve to drive the pump, and then close the electromagnetic switching valve after a certain period of time has elapsed. Hydraulic drive circuit for the vibration damping device.
