摘要： In a steplessly adjustable hydropneumatic device the spring chamber of which is arranged at the piston rod exit end and which works with a liquid locking, a very simple hydraulic locking is obtained even for high traction stressing upon the piston rod in that both an annular separator piston and the partition are arranged in the inner chamber of the container, which is penetrated by the piston rod. For the hydraulic traction locking in the case of traction forces exerted suddenly upon the piston rod a valve device is provided which cooperates with the piston rod.

摘要： A gas spring is provided in an illustrational example between a framework and a trunk cover of a motor vehicle for compensating for the weight of the trunk cover during movement of said trunk cover. The gas spring is hinged to the framework and to the trunk cover. For eliminating the spring force action on the hinge between the trunk cover and the gas spring in the closed position of the trunk cover, the part of the gas spring hinged to the trunk cover is supported on the framework, when the trunk cover is in its closed position. Alternately, the gas spring is locked when the trunk cover is in its closed position.

摘要： According to an illustrative example of the invention, a chair column comprises a base tube with a support plate. A gas spring is accommodated within the base tube. The piston rod of the gas spring is supported on the base tube by a ball bearing. The cylinder of the gas spring is guided at the upper end of the base tube by a guiding sleeve. The guiding sleeve is telescopical with respect to the base tube in response to outward and inward movement of the cylinder with respect to the base tube such that a full satisfactory guiding function is maintained between the cylinder and the base tube, even when the cylinder is in its uppermost position.

摘要： According to an illustrative example of the invention a gas spring has adjacent one end thereof an axially extending control pin. This control pin is prestressed towards an outer position and can be pushed inwards for opening a valve, which valve is provided in the passage between two working chambers established by a piston, said piston being fixed to a piston rod. When the pin is in its outward position, the gas spring is locked in the respective axial length. When the control pin is moved inwards, the axial length of the gas spring can be varied. The gas spring is intended for combination with a chair or table column. In combining the gas spring with a chair, the upper end of the gas spring cylinder is fixed to the lower side of the seat plate. The lower side of the seat plate is provided with a manipulating level. The manipulating lever engages the outer end of the control pin through a telescopic arrangement of control members or adapter elements. These control members can be adjusted with respect to each other in axial direction by axial movement without relative rotation during the axial movement. After the correct length of the telescopic arrangement has been adjusted, the telescopic members are fixed with respect to each other.

摘要： A pneumatic strut for use as an opening power assist mechanism for a motor vehicle tailgate has a piston rod extending from a piston contained within a cylinder. The piston separates the cylinder into two work chambers, each containing a gas charge under pressure. A bypass opening is active to connect the work chambers during the initial opening displacement of the tailgate to automatically open the tailgate through a first opening angle range. A second valve can be externally actuated to connect the two work chambers to further selectively open the tailgate into a second opening angle range. To close the tailgate, a third, directionally dependent valve can automatically connect the two work chambers during the closing displacement of the tailgate.

摘要： A positioning device is used for the positioning of a chair seat as to its inclination, or for positioning a back-rest member of a chair. The positioning device is constructed such as usual hydropneumatic springs which can be locked by closing a passage connected to working chambers on both sides of a piston. The working chambers are filled with an operating liquid. In order to adapt the biasing force of such a positioning device, one of the working chambers is conneced with a force-measuring device, which force measuring device is provided within the force transmission path of the respective chair column. The force measuring device comprises a measuring space filled with operating liquid, and this operating liquid is in liquid connection with one of the working chambers.

摘要： A positioning device is e.g. used for positioning the door of a motor vehicle in an opened position. The positioning device comprises e.g. a cylinder and a piston rod which extends inward and outwards of the cylinder through one end thereof. A flank face is provided at the inner wall surface of the cylinder. The piston rod carries a piston. The piston is provided with a counter-arresting ring which engages the flank face in a predetermined position. When the piston passes across the arresting flank of the cylinder, the counter-arresting ring is moved radially inwards with respect to the axis of the piston rod against elastic resistence. So, an increased resistance occurs against the axial movement of the piston rod with respect to the cylinder. This increased resistance against axial movement positions the door with respect to the body frame of a motor vehicle in a predetermined opened position and avoids that the door is closed unintentionally. Af the flank face and the arresting ring are enclosed within the cavity of the cylinder, they are not subject to environmental conditions, which might deteriorate their positioning function after a period of use. Lubricating agent may be provided within the cavity for lubricating the flank face and the arresting ring. As such lubricating agent is enclosed within the cavity of the cylinder, there is no risk for the vehicle driver to be polluted by the lubricating agent.
摘要翻译：定位装置是例如用于将机动车辆的门定位在打开位置。定位装置包括：气缸和活塞杆，其通过其一端向内和向外延伸。在气缸的内壁表面设有一个侧面。活塞杆带有活塞。活塞设置有止动环，该止动环在预定位置接合该侧面。当活塞穿过气缸的止动侧面时，防止止动环相对于活塞杆的轴线径向向内移动以抵抗弹性阻力。因此，抵抗活塞杆相对于气缸的轴向运动发生增加的阻力。这种增加的抵抗轴向运动的阻力将门相对于机动车辆的车身框架定位在预定的打开位置，并且避免了门被无意地关闭。在侧面和止动环之间封闭在气缸的空腔内，它们不受环境条件的影响，在使用一段时间后可能会使其定位功能恶化。可以在空腔内设置润滑剂以润滑侧面和止动环。由于这种润滑剂被封装在气缸的空腔内，所以车辆驾驶员不会被润滑剂污染的风险。

摘要： In a gas spring the piston rod is guided through one end of a container. Adjacent to this one end two sealings are provided in axial direction one behind the other, namely an axially outer sealing and an axially inner sealing. A liquid chamber is defined between the axially outer sealing and the axially inner sealing. The axially inner sealing comprises a sealing ring of elastomeric material. This sealing ring comprises a radially outer root portion and a radially inner lip portion. The root portion engages an internal circumferential surface of the container tube. The lip portion engages an external circumferential surface of the piston rod. The axial dimension of the root portion is substantially larger than the axial dimension of the lip portion. The sealing ring may be deflected by pressure differences on both sides of the sealing ring such that a fluid exchange is possible between both axial sides of the sealing ring when the pressure difference exceeds a predetermined value.
