<P>PROBLEM TO BE SOLVED: To provide a hydraulic device having freedom in a device layout, effectively taking out hydraulic power and using inertia. <P>SOLUTION: The hydraulic device 10 is equipped with a hydraulic pump driven by a driving source 14, a hydraulic pump motor 52 driven by operating fluid discharged from the hydraulic pump and flowing through an oil path 50, an inertial body 60 connected to a rotating shaft of the hydraulic pump motor, an oil path 62 connected between an outflow port in the hydraulic pump motor and load 22, an unload oil path 64 branched from the oil path 62, and an opening/closing valve 68 interposed in the unload oil path. In this configuration, when opening and closing the opening/closing valve, high pressure is generated in the oil path 62 by using a kinetic energy of the inertial body. By driving the inertial body by hydraulic power, the driving source and the inertial body are separated to enhance the freedom in the device layout. <P>COPYRIGHT: (C)2004,JPO |
