    • A gas spring includes a vertical cylinder, a piston rod extending out of the cylinder through the upper end thereof, a rod guide provided on the upper end of the cylinder for guiding the piston rod, a first seal mounted on the rod guide, a partition wall provided in the cylinder to partition the interior thereof into an upper oil chamber and a lower gas chamber, and a second seal cooperating with the partition wall and slidingly engaging with the piston rod. At least two normally closed first passages are provided in the rod guide and communicate the interior of the cylinder with the outside when filling gas and in filling oil into the cylinder, and a second passage is provided to communicate the gas chamber with the oil chamber when filling gas into the gas chamber.
    • 气弹簧包括垂直气缸,活塞杆,其从气缸的上端延伸出气缸,设置在气缸上端的导杆,用于引导活塞杆,安装在杆导向件上的第一密封件,分隔件 设置在气缸中的壁将其内部分隔成上部油室和下部气体室,以及与分隔壁配合并与活塞杆滑动接合的第二密封件。 至少两个常闭的第一通道设置在杆引导件中,当填充气体并将油填充到气缸中时,将气缸的内部与外部连通,并且设置第二通道以将气室与油室连通, 将气体充入气室。

    • A method for filling gas into a cylindrical container having a rod slidably extending from one end thereof. The method comprises forming passage means in the rod at a position adjacent to the inner end thereof, projecting the rod outwardly to its maximum extending position so as to form a gas filling passage by said passage means across an annular seal member which normally engages the rod sealingly and slidably, filling high pressure gas into the container through the gas filling passage, and moving the rod inwardly relative to the seal member to close the gas filling passage.
    • 一种用于将气体填充到具有从其一端可滑动地延伸的杆的圆柱形容器中的方法。 该方法包括在邻近其内端的位置处形成杆中的通道装置,将杆向外突出到其最大延伸位置,以便通过所述通道装置形成通过环形密封构件的气体填充通道,所述环形密封构件通常与杆 密封地和可滑动地,通过气体填充通道将高压气体填充到容器中,并且使杆相对于密封构件向内移动以关闭气体填充通道。
