    • Hydrogen gas flow from high pressure storage to a lower pressure hydrogen-using device is managed using one or more axial flow pressure regulators comprising a cup-shaped housing with an inlet for high pressure hydrogen gas at one end of the flow axis and a closure with a low pressure hydrogen outlet at the other end of the flow axis. A piston head with a piston stem are aligned on the flow axis and a hydrogen flow passage is formed up the stem and through the piston head to the hydrogen flow outlet. One or more combinations of a corrugated tubular bellows (or like expansive sealing vessel) with static seals attaching one bellows end to the piston stem or head and the other bellows end to the housing or closure are used to accommodate axial movement of the piston while isolating and containing hydrogen gas flow from a high pressure chamber at a flow entrance to the piston stem to a low hydrogen pressure chamber at the piston head and closure outlet.
    • 使用一个或多个轴向流量调节器来管理从高压储存器到低压氢气使用装置的氢气流,所述轴流式流量调节器包括具有在流动轴线的一端具有用于高压氢气的入口的杯形壳体,以及具有 在流动轴的另一端的低压氢出口。 具有活塞杆的活塞头在流动轴线上对准,并且氢气流动通道形成在杆上并且通过活塞头到达氢气出口。 波纹管状波纹管(或类似膨胀密封容器)的一个或多个组合,其具有将一个波纹管端部附接到活塞杆或头部的静态密封件以及将另一个波纹管端部连接到壳体或封闭件的静态密封件用于容纳活塞的轴向运动,同时隔离 并且包含来自在活塞杆的流入口处的高压室的氢气流到活塞头和封闭出口处的低氢压力室。
