    • A reduced weight and repairable piston accumulator. The accumulator includes a load bearing metallic cylinder with removable end caps secured thereto with slip flanges for allowing repairability and for achieving the required cycle life. The cylinder serves as the surface on which the piston slides and is designed such that it sustains the axial stress induced by pressurization of the accumulator. A composite over wrapping is designed such that it sustains the stress in the hoop (radial) direction. A stress transitioning bushing can be provided for transitioning hoop stresses between the overwrap and the slip flange. When combined with the cylinder, the fibers of the composite wrap will not be placed in shear and thus will not fatigue in the same manner as some prior art designs.
    • 减重和可修复的活塞蓄能器。 蓄能器包括承载金属圆筒,其具有固定到其上的滑动凸缘的可拆卸的端盖,用于允许可修复性并实现所需的循环寿命。 气缸用作活塞滑动的表面,并被设计成使得其保持由蓄能器的加压引起的轴向应力。 设计复合材料以使其在箍(径向)方向上承受应力。 可以提供应力转变衬套,用于在外包装和滑动凸缘之间过渡环向应力。 当与圆筒组合时,复合包裹物的纤维将不会被放置在剪切中,因此不会像现有技术设计中那样相同的方式疲劳。

    • A pressure vessel for receiving at least one fluid medium has a first shell (1) and a second shell (3) at least partially encompassing the first shell (1). The first shell (1) has, at least at one of its ends, a collar portion (5) having a securing element (15) that forms an opening (13) for supplying and discharging the medium. A support element (19) in the form of a split ring surrounds the opening (13), is provided inside the container and has a contact surface (39) adapted to the curved shape of the first shell (1) inner side attached to the collar portion (5). The contact surface is able to be pressed onto the first shell inner side attached to the collar portion (5). The contact surface is able to be pressed onto the first shell (1) using a pressing device (43, 45).
    • 用于容纳至少一种流体介质的压力容器具有至少部分地包围第一壳体(1)的第一壳体(1)和第二壳体(3)。 第一壳体(1)至少在其一个端部具有一个带有一个形成用于供应和排出介质的开口(13)的固定元件(15)的凸缘部分(5)。 围绕开口(13)的开口环形式的支撑元件(19)设置在容器内部,并且具有适于连接到第一壳体(1)的内侧的弯曲形状的接触表面(39) (5)。 接触表面能够被压到附接到轴环部分(5)的第一壳体内侧。 接触表面能够使用压制装置(43,45)压在第一壳体(1)上。
