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： An adjustable speed gas spring primarily adapted for use as a part of a door closing mechanism. The gas spring includes a piston assembly which is disposed within an elongated fluid chamber and which upon relative rotation of the shaft with respect to the tubular body, permits the user to adjust the shaft extension velocity. The gas spring is fully functional in any shaft orientation.

摘要： A seal that is particularly suitable for use in a gas spring (and other high pressure hydraulic and pneumatic sealing applications) and that minimizes leakage of relatively high pressure gas and lubricating oil from the rod end of the gas spring. The generally annular seal body includes a radially inwardly facing surface, force directing lobes and either a plastic wiper insert or a wiper lobe that are designed for minimizing the leakage of oil between the radially inwardly facing surface of the seal body and the adjacent, radially outwardly facing surface of the gas spring's piston rod, and that include a corner edge that projects radially inwardly beyond the plane of the seal body's radially inwardly facing surface. When the seal body is compressed for use in a gas spring and is thus subjected to the high-pressure gas, the induced stresses in the seal body result in the corner edge being forced against the adjacent surface of the piston rod to effectively prevent the leaking of oil therebetween. The permeation of gas axially through the seal body is minimized by the inclusion of a co-molded metal plate in the seal body adjacent to the rod end of the seal body.
摘要翻译：特别适用于气弹簧（和其他高压液压和气动密封应用）的密封件，并且能够最大程度地减少气弹簧杆端的相对高压气体和润滑油的泄漏。大体上环形的密封体包括径向向内的表面，其作用是引导凸角和塑料擦拭器插入件或擦拭器凸片，其被设计用于最小化在密封体的径向向内的表面与相邻的径向向外的油之间的泄漏气弹簧的活塞杆的面对表面，并且包括径向向内突出超过密封体径向向内表面的平面的角边缘。当密封体被压缩以用于气体弹簧并且因此受到高压气体时，密封体中的感应应力导致角部边缘被迫抵靠活塞杆的相邻表面以有效地防止泄漏的油之间。通过在与密封体的杆端相邻的密封体中包括共模塑金属板，使气体轴向穿过密封体的渗透被最小化。
