    • An accumulator for a hydraulic system includes a polymer liner defining a cavity. A metal bellows assembly is housed in the cavity and separates the cavity into a first chamber and a second chamber, with the first and second chambers isolated from one another by the bellows assembly. A composite shell substantially encases the liner. The liner and shell are configured so that the first chamber receives hydraulic fluid from and delivers hydraulic fluid through an opening in the liner and the shell as the bellows assembly expands and compresses due to pressurized gas in the second chamber balancing fluid pressure changes in the first chamber. In one embodiment, the metal bellows assembly includes hydroformed bellows.
    • 用于液压系统的蓄能器包括限定空腔的聚合物衬垫。 金属波纹管组件容纳在空腔中并将空腔分离成第一室和第二室,其中第一和第二室通过波纹管组件彼此隔离。 复合外壳基本上包住衬垫。 衬套和外壳被构造成使得当波纹管组件由于第二室中的加压气体而膨胀和压缩时,第一腔室接收液压流体并通过衬套和壳体中的开口输送液压流体,以平衡第一腔室中的流体压力变化 房间。 在一个实施例中,金属波纹管组件包括液压成形波纹管。

    • Apparatus for attaching internal parts to the interior of a pressure vessel having an inner lining of uncured rubber includes a rigid fastener, preferably an internally threaded nut, rigidly secured over an opening through the wall of the vessel and the rubber lining. A rigid bolt is threaded through the nut from the inside of the vessel so that a lateral shoulder on the bolt is tightened against the rubber lining. A layer of uncured rubber is mounted over the shoulder, and the layer is cured when the inner lining is being cured to embed the shoulder in the rubber and seal the bolt against leakage. Internal parts are attached to the portion of the bolt inside the vessel, and the structural load applied to the bolt by the internal parts is transmitted to the wall of the vessel through the rigid bolt and nut.
    • 用于将内部部件附接到具有未固化橡胶内衬的压力容器内部的装置包括刚性紧固件,优选内螺纹螺母,刚性地固定在通过容器壁和橡胶衬里的开口上。 刚性螺栓从容器的内部穿过螺母,使得螺栓上的横向肩部紧固在橡胶衬里上。 未固化的橡胶层安装在肩部上,当内衬被固化以将肩部嵌入橡胶中时,该层被固化,并且密封螺栓以免泄漏。 内部部件连接到容器内的螺栓部分,并且内部部件施加到螺栓的结构载荷通过刚性螺栓和螺母传递到容器的壁。
