摘要： An impact damper for a motor vehicle comprises two fluid chambers. These fluid chambers are interconnected by a fluid passage. In case of an impact of the motor vehicle against an obstacle, the fluid flows from one fluid chamber to the other fluid chamber through the throttled passage. If the impact occurs with a high velocity beyond a predetermined velocity, the impact damper behaves like a rigid body. It may therefore occur that the vehicle is damaged to a higher degree than it would in case of lack of the impact damper. For preventing such situation, the passage is provided by perforated and sandwiched discs. One disc acts as a support disc, one other disc acts as a throttling disc. The throttling disc is provided with a weakening line and is broken at a predetermined pressure different between the two fluid chambers. After rupture has occurred, the flow resistance through the passage is reduced and therefore the rigid behavior of the impact damper is eliminated.

摘要： In a cylinder piston device the piston when approaching the end of the cylinder abuts against an indentation of the cylinder and is tilted or angled by the abutment, on the one hand, and by an axially directed force acting onto the piston rod, on the other hand. Thus, a clamping effect is obtained. By the clamping effect expulsion of the piston rod is prevented. Moreover, the tilting may result in a leakage condition of sealing rings. This allows pressurized fluid to escape. As a result, an increased security in case of high temperature development by fire is obtained.
摘要翻译：在气缸活塞装置中，接近气缸端部的活塞抵靠气缸的凹陷，并且一方面由邻接部分和另一方面作用在活塞杆上的轴向力作用而倾斜或成角度手。因此，获得了夹紧效果。通过夹紧效果可以防止活塞杆的排出。此外，倾斜可能导致密封圈的泄漏状况。这允许加压流体逸出。结果，获得了由火灾高温发展的情况下增加的安全性。

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。
