    • 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 hydro formed 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,平衡第一腔室中的流体压力变化 室。 在一个实施例中,金属波纹管组件包括液压波纹管。

    • A pressure accumulator includes a housing having a housing cavity, a piston axially displaceable in the housing cavity between a first final position and a second final position and having a pressure surface which together with a wall of the housing cavity delimits at least partially a reservoir connectable to an ICE consumer in a fluid-conveying manner, an energy store cooperating with the piston, the piston being displaceable against the force of the energy store from the first final position into the second final position in that the reservoir is acted on by pressure using a pressure medium, and a locking device for locking the piston in the second final position. A locking tube is connected to the piston and supported within the housing in an axially shiftable manner, and lockable at an end of the housing facing away from the reservoir with the aid of a locking pin.
    • 压力储存器包括具有壳体空腔的壳体,在第一最终位置和第二最终位置之间在壳体空腔中可轴向移动的活塞,并具有压力表面,该压力表面与壳体腔室的壁一起至少部分地限定了可连接的储存器 以流体输送方式连接到ICE消费者,能量储存器与活塞配合,活塞能够抵抗能量储存器的力从第一最终位置移动到第二最终位置,因为储存器通过压力作用 压力介质和用于将活塞锁定在第二最终位置的锁定装置。 锁定管连接到活塞并以可轴向移动的方式支撑在壳体内,并且借助于锁定销可锁定在壳体的远离储存器的端部处。
