The system uses the engine to drive a hydraulic pump that charges an accumulator to highpressure.
这种系统利用该发动机来驱动液压泵以使蓄压器充满压力达到高压。

The highpressure liquid in the accumulator (with potential energy) enters the working cylinder in a flash and the potential energy converts to kinetic energy.
蓄势器内的高压液体(具有势能)进入工作缸是在瞬时之间进行的，具有势能转变为动能作功的特点。

Accumulator is used in hydraulic press driven by pump-accumulator. The highpressure pump with small flow can put working liquid into the accumulator in the intermittent working time of press.
