    • A suspension strut for a vehicle comprises a cylinder in which works a piston, and the piston is carried by a piston-rod which passes through an axial extension depending from a closure for one end of the cylinder. An annular chamber defined between the cylinder and the extension accommodates the whole of a volume of gas or air and a portion of a volume of hydraulic fluid which fills the remaining space in the cylinder and against which the piston works. A seal through which the piston-rod works is carried by the extension at a position which is always below the level of hydraulic fluid in the cylinder so that the gas or air is prevented from escaping past the seal by the presence of the hydraulic fluid.
    • 用于车辆的悬架支架包括一个气缸,其中工作活塞,并且活塞由活塞杆承载,该活塞杆穿过从气缸一端的闭合件延伸的轴向延伸。 限定在气缸和延伸部之间的环形室容纳整个体积的气体或空气,以及一部分体积的液压流体,其填充气缸中的剩余空间并且活塞在其上工作。 活塞杆工作的密封件由延伸部承载在总是低于气缸中的液压流体水平的位置处,使得气体或空气通过存在液压流体而被防止从密封件逸出。
