    Abstract: PURPOSE: A construction machine is provided to recover energy securely, and to reduce the size of the battery or the generator by charging remaining energy in the battery and actuating the generator with remaining torque. CONSTITUTION: A construction machine has an engine(1), a hydraulic pump(2) driven by the engine, and actuators(4) driven by discharge oil from the hydraulic pump. A regenerative motor(8) is rotated by return oil from the actuators and connected to a rotary shaft of the hydraulic pump. If driving torque necessary in the hydraulic pump is higher than output torque generated by the operation of the regenerative motor, the hydraulic pump operates driven by the engine and the regenerative motor. If driving torque for the hydraulic pump is lower than output torque of the regenerative motor, the hydraulic pump operates by the regenerative motor. With excess torque not subjected to energy regeneration in the hydraulic pump, a generator(11) connected to the rotary shaft of the hydraulic pump is operated for power generation to charge a battery(12) with the generated output.

    Abstract translation: 目的：提供建筑机械，以便能够安全地回收能量，并通过在电池中充电剩余能量并以剩余的转矩来驱动发电机来减小电池或发电机的尺寸。 构成：建筑机械具有发动机（1），由发动机驱动的液压泵（2）和由液压泵排出的油驱动的致动器（4）。 再生电动机（8）由来自致动器的返回油旋转并连接到液压泵的旋转轴。 如果液压泵所需的驱动扭矩高于由再生电动机的运转产生的输出转矩，则液压泵由发动机和再生电动机驱动。 如果液压泵的驱动扭矩低于再生电机的输出转矩，则液压泵由再生电机运转。 由于在液压泵中没有进行能量再生的过剩扭矩，与液压泵的旋转轴连接的发电机（11）进行发电，以产生电力来对蓄电池（12）充电。

    Abstract: A hydraulic machine includes a number of piston/cylinder units which are each controlled by valves positioned upstream and downstream. The valves are in turn activated by an electronic regulator to switch the hydraulic machine selectively into a pump operating mode and a motor operating mode. The regulator selectively switches the individual piston/cylinder units or unit groups separately from one another into individually selectable operating modes as a function of certain regulating variables.
