The same effect happens when in reverse, transferring the otherwise wasted magnetic charge to the forward battery.

同样的效果发生时，在扭转，转让，否则浪费了磁荷向前进电池。

The technology works by capturing and recycling otherwise wasted pressure energy in fluid flows, by a clean liquid-to-liquid energy exchange between high pressure and low pressure fluids.

该技术的工作原理是在高压和低压流体之间通过一个清洁的液体能量交换设备，捕获和再循环本将浪费掉的液压能。
