摘要： A variable-damping liquid spring having a housing adapted to contain a compressible fluid under pressure, a piston means extending into the said housing in slidable sealing engagement therewith, and damping means positioned within said housing which provide a variable fluid flow pattern to permit changes in the rate or direction of fluid flow within the housing during relative movement between the piston means and housing. A plurality of sleeves may be mounted within the housing with each of the sleeves having apertures therein. One fluid flow pattern during relative movement between the piston means and housing is established by the flow alignment of one set of apertures in the sleeves and another flow pattern during relative movement between the piston means and housing is established by the flow alignment of a different set of apertures in the sleeves.
摘要翻译：一种可变阻尼液体弹簧，其具有适于容纳处于压力下的可压缩流体的壳体，以可滑动的密封接合方式延伸到所述壳体中的活塞装置，以及设置在所述壳体内的阻尼装置，其提供可变流体流动模式，在活塞装置和壳体之间的相对移动期间，壳体内的流体流动速率或方向。多个套筒可以安装在壳体内，每个套筒在其中具有孔。在活塞装置和壳体之间相对移动期间的一个流体流动模式通过套管中的一组孔的流动对准来确定，并且在活塞装置和壳体之间的相对运动期间通过不同组的流动对准来建立另一个流动模式的袖子中的孔。

摘要： A barrier post which is angularly movable at a predetermined angle from vertical upon impact at any angle, the point of the angular movement is damped by movement of a viscous material past a piston within a cylinder. The exterior surface of the post is formed to frictionally restrain the impacting object against upper sliding movement along the post. A group of such posts are to be employed to effect complete absorption of the impact force.
摘要翻译：阻挡柱在任何角度以冲击的方式以垂直方向成角度地移动，角运动的点通过粘性材料通过气缸内的活塞的运动而衰减。柱的外表面被形成为摩擦地限制冲击物体抵抗沿着柱的上部滑动运动。将采用一组这样的岗位来完全吸收冲击力。
