PROBLEM TO BE SOLVED: To provide a fluid pressure control device which enables an accumulator to reach a preload early.SOLUTION: A fluid pressure control device includes at least: a pump 2 for discharging a working fluid; a booster 7 which increases a pressure of the working fluid discharged from the pump 2 to discharge the working fluid; and an accumulator 8 which accumulates the pressure of the working fluid discharged from the booster 7. The booster 7 has: a driving chamber 72 into which the working fluid discharged from the pump 2 is introduced; and a communicating chamber 74 which communicates with the accumulator 8 and increases the pressure of the working fluid to a pressure higher than a discharge pressure of the pump 2 to discharge the working fluid. The fluid pressure control device has a selector valve 6, which may switch a passage of the working fluid between the driving chamber 72 and the communicating chamber 74, between the pump 2 and the booster 7.SELECTED DRAWING: Figure 1 |
