<p><P>PROBLEM TO BE SOLVED: To convert a standby flow amount into energy while using the standby flow amount of first and second main pumps MP1, MP2 for generating power. <P>SOLUTION: Pilot flow paths 11, 22 are connected to the upstream sides of on-off valves 10, 21. When the first and second main pumps MP1, MP2 secure the standby flow amount, the on-off valves 10, 21 are closed. A controller C determines that the first and second main pumps MP1, MP2 discharge the standby flow amount in accordance with pressure signals from first and second pressure sensors 13, 24, and sets first and second solenoid valves 58, 59 at open positions. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
