A single - direction valve controlled by liquid, an accumulator and hydraulic pumps can be used to keep pressure in hydraulic systems.
液压系统可以采用液控单向阀、蓄能器、液压泵等多种形式实现保压。
The high pressure 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。
The accumulator collects gaseous and liquid refrigerant passing from the evaporator to the compressor.
储液器收集从蒸发器流通到压缩机的气态和液态制冷剂。
Accumulator is used in hydraulic press driven by pump-accumulator. The high pressure pump with small flow can put working liquid into the accumulator in the intermittent working time of press.
泵-蓄势器传动的液压机，由于采用了蓄势器，故只用流量较小的高压泵。
