<p><P>PROBLEM TO BE SOLVED: To provide a hydraulic reproduction system which accumulates and uses reproduced hydraulic energy. <P>SOLUTION: A hydraulic system is provided for a working machinery. The hydraulic reproduction system is provided with a tank, a source of primary pressurization, a first actuator, an accumulator and a first valve mechanism. The tank is constructed so as to retain a fluid of amount of supply. The source of primary pressurization pressurize fluid and is constructed to include an intake inlet and a discharge outlet. The first actuator is constructed to receive a pressurized fluid from the discharge outlet of the source of primary pressurization. The accumulator is fluidly connected with the tank, the intake inlet of the source of primary pressurization and the first actuator. The first valve mechanism is disposed between the intake inlet of the source of primary pressurization and the accumulator. The first valve mechanism is also movable between first position where fluid returning from the first actuator is oriented to the intake inlet of the source of primary pressurization and second position where fluid returning from the first actuator is oriented only to the accumulator. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
