    • An inexpensive pressure vessel which can be disposed of rather than being repaired once it fails, which includes a cylindrical housing having two chambers separated by a resilient bladder. One chamber is for housing a gas while the second is for housing a fluid such as hydraulic oil. The cylindrical housing contains a port at one end and is open at the opposite end. The end cap which contains a through port and a gas valve is insertable into the open end of the cylindrical housing and is welded thereto. This weld joint in conjunction with a seal formed by attaching the resilient bladder to the end cap, will positively seal the pressure vessel. The unique seal between the end cap, bladder and housing is such that it will not be thermally damaged by the welding process which seals the end cap to the cylindrical housing.
    • 一种廉价的压力容器,其可以被处理而不是一旦被修复失效,其包括具有由弹性囊隔开的两个腔室的圆柱形壳体。 一个腔室用于容纳气体,而第二个用于容纳诸如液压油的流体。 圆柱形壳体在一端包含一个端口,在另一端开放。 包含通孔和气阀的端盖可插入圆柱形壳体的开口端并焊接到其上。 该焊接接头与通过将弹性囊附接到端盖形成的密封件将会正确地密封压力容器。 端盖,气囊和壳体之间的独特的密封件使得不会通过将端盖密封到圆柱形壳体的焊接过程而被热损坏。
