摘要： Self-pumping hydropneumatic suspension strut unit with internal level control, with an oil-filled working cylinder subject to the pressure of gas cushions and with a damping piston, which is free to slide inside the cylinder and is mounted at the end of a hollow piston rod, the cavity of which serves as a pump cylinder for a pump rod attached to the working cylinder. Oil is drawn from a reservoir space when the piston rod travels outward, whereas the oil is conveyed into the working space when the piston rod travels inward. The pump rod passes through the end wall of the working space and is held axially in position by an end-mounted disk, which acts as a universal joint for the rod, and the disk engages in a groove in the pump rod and is held in place by its outer circumference axially between the working cylinder and the end wall of the working cylinder. The disk has a slot to accept the pump rod, the first area of this slot having a diameter corresponding to the base of the groove, whereas the second area has a diameter corresponding to the outside diameter of the pump rod.

摘要： A piston cylinder assembly which includes a work cylinder, a piston and a piston rod, which piston rod carries the piston and extends out of the work cylinder in a sealed manner, as well as a ring-shaped equalization chamber formed by two tubes is disclosed. The equalization chamber is divided by a separating piston into two partial chambers, the separating piston having two parts which are guided so that they can move in a sealed manner axially on the wall of the respective tube of the compensation chamber facing the respective part. The two parts of the separating piston are connected by a flexible portion allowing them to move radially with respect to one another and are sealed with respect to one another.

摘要： Guide for the piston rod of a piston-cylinder assembly, especially for a vibration damper, a shock-absorbing strut, or a level-control device. The guide has a guide body with an outer end surface holding a piston rod seal, where the piston rod is installed in the guide and sealed with freedom to move in the axial direction. The piston rod seal has an axial extension opposite the piston-cylinder assembly, which extension is held in an annular recess in the end surface, which recess is spaced from the piston rod and coaxial to the piston rod.

摘要： A simple, operationally reliable and not-overly-sensitive level control in a generally known form of self-pumping hydropneumatic spring leg or strut is of such a construction that a delayed adjust-down control action can be achieved when a control opening is opened upon reaching a certain level. For that purpose, a sleeve is fitted as or as part of a throttle arrangement between the control opening of a hollow pump rod and a suction valve arranged at the end of the pump rod, the sleeve allowing oil to flow with a delay from the high pressure chamber which controls the level, by way of the control opening of the pump rod to the pump rod bore, the bore communicating with a low pressure chamber from which oil is normally pumped to the high pressure chamber. By removing the throttling responsibility from the control opening, size restrictions on the control opening are removed, thus facilitating sizing the control opening so as to preclude clogging. The throttling and delay functions can be accomplished by appropriately sizing the length and cross section of a duct defined in part by the sleeve, or by a throttle opening defined in part by the suction valve. In the latter arrangement, a self clearing action is achieved when the suction valve lifts from its seat.
摘要翻译：通常已知形式的自抽水合气动弹簧腿或支柱的简单，操作可靠和不过分敏感的液位控制具有这样的结构，即当控制开口打开时可以实现延迟的调节控制动作达到一定水平。为此，在中空泵杆的控制开口和布置在泵杆端部的吸入阀之间，将套筒作为或作为节流装置的一部分安装，套筒允许油从高温延迟流动通过泵杆到泵杆孔的控制开口来控制水平面的压力室，该孔与低压室连通，油从其通常被泵送到高压室。通过去除控制开口的节流责任，去除了控制开口的尺寸限制，从而便于调整开口尺寸，防止堵塞。节流和延迟功能可以通过适当地确定由套管部分限定的管道的长度和横截面，或通过由吸入阀部分限定的节气门开度来实现。在后一种布置中，当抽吸阀从其座椅上升时，可以实现自清除动作。

摘要： Guide for the piston rod of a piston-cylinder assembly, especially for a vibration damper, a shock-absorbing strut, or a level-control element, where the guide body holds the cylinder tube and the outside tube and simultaneously centers the piston rod in a central bore. The guide body has two axially spaced sealing elements which rest on the outside surface of the piston rod and seal off the interior space of the piston-cylinder assembly from the atmosphere. A flow connection, starting from the area of the intermediate space between the seals, extends to the interior space and is provided with a nonreturn valve, through which a flow can proceed only in the direction of the interior space.

摘要： An impact damper which is equipped with an economical, cost-effective work piston, on which not only can a weight reduction be made, but also a substantial simplification in manufacture can be achieved. This impact damper is also designed to be deformable instantaneously upon collision with an obstacle when the force of the collision exceeds a predetermined range. The work piston is designed as a tubular body closed on a side facing a fluid containing chamber, and is provided with a breaking or buckling point, whereby energies can readily be absorbed, even at relatively high impact velocities.
摘要翻译：一种冲击阻尼器，其配备有经济，经济有效的工作活塞，其不仅可以减轻重量，而且可以实现制造的实质简化。该冲击阻尼器还设计成当碰撞力超过预定范围时与障碍物碰撞时瞬间变形。工作活塞被设计为在面向流体容纳室的一侧封闭的管状体，并且设置有断裂或屈曲点，由此即使在相对较高的冲击速度下，能够容易地吸收能量。
