<P>PROBLEM TO BE SOLVED: To provide a fluid pressure source system of high practicality. <P>SOLUTION: The fluid pressure source system includes: a fluid pressure source device 34 having (a) a pump 30 which discharges working fluid and (b) an accumulator 32 of which the inside is divided into a working fluid chamber and a gas chamber by a partition member and accumulates the working fluid discharged from the pump in the working chamber; and an electric control unit 60 for controlling an operation of the pump. The electric control unit 60 starts the operation of the pump when an accumulator pressure falls below the lower limit threshold, stops the operation of the pump when the accumulator pressure exceeds the upper limit threshold, and further changes at least one of the lower limit threshold and the upper limit threshold on the basis of a temperature of the accumulator. According to the fluid pressure source system, the volumetric change of the working fluid chamber and the gas chamber and a change in deformation of the partition member are relatively small. <P>COPYRIGHT: (C)2012,JPO&INPIT |
