    • A lightweight, optimally efficient, easily serviced, piston-in-sleeve high pressure accumulator is provided. The accumulator includes one or more cylindrical composite pressure vessel separate end cap manifolds. A piston slidably disposed in a thin impermeable internal sleeve in the accumulator separates two chambers, one adapted for containing a working fluid and the other adapted for containing gas under pressure. Gas is provided in a volume between the impermeable internal sleeve and the composite pressure vessel wall. Additional gas is optionally provided in gas cylinders. Further components are provided for withstanding harmful effects of radial flexing of the composite vessel wall under high pressures, and from stresses present in use in mobile applications such as with a hydraulic power system for a hydraulic hybrid motor vehicle.
    • 提供了一种重量轻,效率最高,易于维修的活塞套筒式高压蓄能器。 蓄能器包括一个或多个圆柱形复合压力容器分离的端盖歧管。 可滑动地设置在蓄能器中的薄的不可渗透的内部套筒中的活塞分离两个腔室,一个适于容纳工作流体的腔室,另一个适用于在压力下容纳气体。 气体以不可渗透的内部套筒和复合压力容器壁之间的体积设置。 附加气体任选地设置在气瓶中。 提供了进一步的组件,用于在高压下耐受复合容器壁的径向弯曲的有害影响,以及在诸如用于液压混合动力车辆的液压动力系统的移动应用中使用的应力。

    • A pressure fluid reservoir for supplying pressure fluid to a wheel slip regulating device that is accommodated in a vehicle has a hose membrane that can be partially emptied by suction. The degree of emptying is limited due to the installation of an inner support body that fluid can flow through. The radial expansion of the hose membrane is limited by an outer support element and by a porous casing encompassing the outer support element, which protects the pressure fluid reservoir from bursting in the event that the hose membrane is subjected to brake pressure. The inner support element, the outer support element, and the casing are flexible hoses and are connected in a pressure-tight fashion to tube line connections in such a way that the pressure fluid reservoir according to the invention is placed in the vehicle in the same way as a brake line.
    • 用于将压力流体供应到容纳在车辆中的车轮滑动调节装置的压力流体储存器具有可以通过抽吸部分排空的软管膜。 由于内部支撑体的安装,流体可以流过而排空的程度受到限制。 软管膜的径向膨胀受到外部支撑元件和包围外部支撑元件的多孔壳体的限制,该外部支撑元件在软管膜受到制动压力的情况下保护压力流体储存器免于破裂。 内部支撑元件,外部支撑元件和外壳是柔性软管,并且以压紧方式连接到管线连接,使得根据本发明的压力流体储存器被放置在车辆中 作为制动线路。
