とを特徴とする流体圧供給装置。A fluid pressure pump that increases the pressure of the fluid led from the fluid storage tank to supply pressure fluid to the fluid pressure power conversion device, and a flow rate of the pressure fluid transmitted from the fluid pressure pump to the fluid pressure power conversion device that is not necessary. In a fluid supply device having a flow rate control valve that controls the pressure fluid supplied to the fluid pressure power conversion device to a predetermined flow rate by returning the surplus flow rate to a return flow path which is a flow path leading to a suction port of a fluid pressure pump. , a switching valve is provided in the flow path between the fluid pressure power conversion device and the fluid storage tank, and the return fluid from the fluid pressure power conversion device is directed to the fluid storage tank or the return flow according to the pressure of the fluid discharged from the fluid pump. By switching to a flow path that communicates with the
The return fluid from the fluid pressure power conversion device is guided to the fluid storage tank until the detected pressure reaches a certain pressure, and when the detected pressure exceeds the certain pressure, the return fluid is short-circuited to the return flow path via the flow path. A fluid pressure supply device characterized in that the pressure in the guide-back channel is increased by
