In view of our existing system, we design the structure model of related valve, proving the effect in which the highhydraulicpressure could improve the miniaturization of this structure.
针对我国有关制动系统工况，讨论了气液制动阀结构型式，初步分析了系统油压力与结构轻。

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。

Shale traps gas more tightly than other rock. To extract it, the shale is blasted with huge volumes of fresh water at highpressure, a practice known as hydraulic fracturing, or "fracking".
