摘要： A piston-cylinder unit for shock absorbers or the like is formed with a tubular container surrounding the cylinder and with a piston rod guide and sealing unit mounted at one end of the container with a support for the cylinder at the other end of the container. In order to effect a satisfactory sealing action at the fixing points of the cylinder, the cylinder is formed with a radial indentation.

摘要： In a double-tube vibration damper the cylinder engages by a terminal edge thereof an engagement face of a piston rod guiding and sealing unit. When the piston rod moves in the outward direction with respect to the cylinder, a high pressure occurs in the working chamber adjacent the piston rod guiding and sealing unit. Due to this high pressure damping liquid jets may escape between the terminal edge of the cylinder and the engagement face of the piston rod guiding and sealing unit. These liquid jets may cause foaming within the annular space defined between the cylinder and a container surrounding the cylinder. In view of avoiding such foaming, an annular cover member is provided between the cylinder and the container, which annular cover member prevents the direct entrance of liquid jets into the annular space between the cylinder and the container. This annular cover member is situated such that it extends across the plane of engagement defined by the terminal edge of the cylinder and extends perpendicular with respect to the axis of the cylinder.
摘要翻译：在双管减震器中，气缸的端部边缘与活塞杆引导和密封单元的接合面接合。当活塞杆相对于气缸在向外的方向移动时，在邻近活塞杆引导和密封单元的工作室中产生高压。由于这种高压阻尼液体射流可以在气缸的终端边缘与活塞杆引导和密封单元的接合面之间逸出。这些液体射流可能在气缸和围绕气缸的容器之间的环形空间内引起发泡。鉴于避免这种发泡，在圆筒和容器之间提供环形盖件，该环形盖件防止液体射流直接进入圆筒和容器之间的环形空间。该环形盖构件设置成使得其延伸穿过由圆柱体的端部边缘限定的接合平面，并相对于圆柱体的轴线垂直延伸。

摘要： A hydropneumatic damping device particularly for spring legs of automotive vehicles comprises an inner cylinder, an outer container, a central cavity within the inner cylinder, an annular cavity between the inner cylinder and the outer container, a piston rod with a piston unit, venting passage means between the central cavity and the annular cavity extending across a cavity-closing unit and check valve means associated to said venting passage means. The check valve means comprises an annular check valve member in frictional sliding engagement with the piston rod for axial movement with the piston rod towards a sealing position during inward movement of the piston rod and towards an opening position during the outward movement of the piston rod. First and second abutment means are provided for defining the sealing and the opening position of the annular check valve member, respectively. The second abutment means are axially fixed with respect to the cavity-closing unit by supporting means separated from the cavity-closing unit and fixed with respect to the respective end of the container.

摘要： A shock absorber assembly including a cylinder having a piston and piston rod mechanism movable relative thereto is formed with a hydraulic-mechanical damping system interposed in an annular space defined between the piston rod and the cylinder. The damping characteristics of the system are varied in accordance with the relative movement of the piston rod out of the cylinder by a damping mechanism which includes a spring, an annular member and a damping component operating to vary the cross-sectional area of the damping passage defined therethrough.

摘要： A piston rod particularly for shock absorbers and spring devices has been shown in the illustrative embodiments. The piston rod comprises a tubular member which tubular member is provided with at least one extension of reduced diameter. The extension is intended for being fastened to associated structural members. In view of fluid-tightly closing the interior of the piston rods on at least one of their ends, a closure member is provided within the cavity defined by the extension of reduced diameter. The closure member is fastened to the piston rod by the reduction of the diameter of the piston rod.

摘要： In a shock absorber unit for vehicles of the double-tube type a piston rod guiding member is provided at respective first ends of a cylinder and a container surrounding the cylinder. The first end of the container engagingly surrounds a radially outer face of the piston rod guide member. The container is tube-shaped and has substantially constant wall thickness along its total length. The radially outer surface of the piston rod guiding member is provided with at least one radially inward directed recess or at least one radially outward directed projection. The first end of the container is deformed such as to engage this projection or recess respectively. A sleeve member engagingly surrounds the first end of the container. This sleeve member is also provided with a deformation which deformation is in engagement with the deformation of the container.
