摘要： The orientation insensitive, non-cavitating differential, bi-directional damper has a tubular body defining a closed, elongated chamber that has a first end and a second end. A piston assembly is disposed in and is movable within a portion of the chamber. One end of a piston shaft is connected with the piston assembly and the other end of the shaft extends out of one end of the chamber. Another assembly is disposed in the chamber between the piston assembly and the other end of the chamber. A floating piston is disposed in the chamber and is movable in the chamber between the other assembly and the other end of the chamber. The portion of the chamber between the other end of the chamber and the floating piston is filled with gas while the remainder of the chamber is filled with fluid. The floating piston is spring biased toward the other assembly. Orifices in the piston assembly control the rate of fluid flow across the piston assembly when the piston assembly moves relatively to the tubular body. The orifices in the other assembly control the rate of fluid flow across the other assembly when the piston assembly moves relatively to the tubular body.
摘要翻译：方向不敏感的非气蚀差速双向阻尼器具有限定具有第一端和第二端的封闭细长室的管状体。活塞组件设置在腔室的一部分中并且可在腔室的一部分内移动。活塞轴的一端与活塞组件连接，轴的另一端从腔的一端延伸出来。另一组件设置在活塞组件和腔室另一端之间的腔室中。浮动活塞设置在腔室中并且可以在腔室中在另一组件和腔室的另一端之间移动。在室的另一端和浮动活塞之间的腔室部分充满气体，而腔室的其余部分填充有流体。浮动活塞朝向另一组件弹簧偏置。当活塞组件相对于管状体移动时，活塞组件中的孔口控制流过活塞组件的流体流速。当活塞组件相对于管状体移动时，另一组件中的孔口控制流过另一组件的流体流速。

摘要： A self centering, bi-directional, non-cavitating damper that includes a cylindrical damper body and a piston assembly having a piston reciprocally movable in the damper body and a piston rod connected and movable with the piston. A tube is connected with the piston rod and is spaced about and radially from the damper body so that the tube and damper body may move axially, relative to each other, but are normally positioned in centered positions with respect to each other. First and second plastic washers are positioned between the damper body and the tube. At least one coil compression spring is positioned between the damper body and the tube and biases the washers apart axially to their normal positions. Each washer is prevented from moving apart beyond its normal position, but is movable toward the other washer, against the bias of the spring, when relative movement, from their normal positions, occurs between the damper body and the tube.
摘要翻译：一种自定心的双向非空气阻尼器，包括圆柱形阻尼器主体和活塞组件，该活塞组件具有可在阻尼器本体中往复运动的活塞和活塞杆，活塞杆可与活塞连接并移动。管与活塞杆连接并且与阻尼器主体间隔开并径向离开，使得管和阻尼器主体可以相对于彼此轴向移动，但是通常位于相对于彼此的居中位置。第一和第二塑料垫圈位于阻尼器主体和管之间。至少一个线圈压缩弹簧位于阻尼器主体和管之间，并将垫圈沿轴向偏压到其正常位置。每个垫圈被阻止超出其正常位置移动，但是当相对运动从其正常位置发生在阻尼器主体和管之间时，可抵抗弹簧的偏压朝着另一个垫圈移动。
