摘要： A vibration isolating and damping suspension strut for vehicle undercarriages comprising an elongated cylinder and piston structure wherein the cylinder is divided into opposed chambers which are in communication with each other by flow restrictive passages formed in the piston or in the cylinder wall. When the strut undergoes a retraction stroke of the piston to absorb loads silicone fluid is compressed in the opposed chambers and transferred from the chamber opposite the piston rod to the rod side chamber through the restrictive passages resulting in heating of the fluid. When the strut rebounds or extends its piston rod fluid is forced to flow through the restrictive passages preferably at a more restricted rate. The flow passages are arranged to direct fluid flow toward the outer cylinder borewall to improve heat transfer to the exterior of the strut and minimize heating of the fluid contained in the cylinder chambers, and preferably in such a way as to minimize intermingling with a significant portion of the remaining fluid.

摘要： A vibration isolating and damping suspension strut for vehicle undercarriages comprising an elongated cylinder and piston structure wherein the cylinder is divided into opposed chambers which are in communication with each other by passages formed in the piston and in a flow restricting shuttle valve mounted on the piston rod. When the strut undergoes a retraction stroke of the piston to absorb loads silicone fluid is compressed in the opposed chambers and transferred from the chamber opposite the piston rod to the rod side chamber through passages in the piston only. When the strut rebounds or extends its piston rod fluid is forced to flow through passages in the shuttle valve member and the piston flow passages at a more restricted rate. The piston flow passages and the shuttle valve are arranged to direct fluid flow toward the outer cylinder borewall to improve heat transfer to the exterior of the strut and minimize heating of the fluid contained in the cylinder chambers. Alternate embodiments of the suspension strut have spiral fluid transfer grooves formed on the periphery of the piston or on a cylinder sleeve insert member.
摘要翻译：一种用于车辆起落架的隔振和阻尼悬架支柱，包括细长的气缸和活塞结构，其中气缸被分成相对的腔室，它们通过形成在活塞中的通道和安装在活塞杆上的限流穿梭阀彼此连通。当支柱经历活塞的收缩行程以吸收载荷时，硅氧烷流体在相对的室中被压缩，并且仅通过活塞中的通道从与活塞杆相对的室转移到杆侧室。当支柱反弹或延伸其活塞杆流体被迫以更有限的速率流过梭阀构件和活塞流动通道中的通道时。活塞流动通道和梭阀布置成将流体流向外筒钻孔壁，以改善对支柱外部的热传递，并使包含在气缸室中的流体的加热最小化。悬架撑杆的替代实施例具有形成在活塞周边或气缸套插入件上的螺旋流体传送槽。
