摘要： A shock absorber includes a first end and a second end that reciprocate relative to one another. The shock absorber includes a gas spring chamber, a damping chamber, and a floating piston. The first side of the floating piston is in fluid communication with the gas spring chamber. The second side of the floating piston is in fluid communication with the damping chamber. The gas in the gas spring chamber applies pressure against the floating piston, which applies pressure to the substantially incompressible fluid in the damping chamber. This pressure transfer may be adequate to minimize or prevent cavitation.

摘要： Generally described, aspects of the disclosed subject matter are directed to through-shaft dampers. In accordance with aspects of the present disclosure, the through-shaft dampers generally include a shaft having a piston traveling within a body, a first chamber for a damping fluid, and a second chamber for a gas. The chambers are separated by a movable wall associated with an insert and configured to provide a volumetric change of the second chamber that is inverse to a volumetric change of the damping fluid. The insert is configured such that the sealing surfaces of the movable wall do not interface the shaft during use of the damper. In this regard, a significant reduction in the total displacement traveled by the seals is realized.

摘要： A hydraulic damper (3) includes a tube (4), a piston assembly (5) disposed slidably inside the tube (4), and an additional valve assembly (13). A compression chamber (9) is defined between the piston assembly (5) and the additional valve assembly (13). An additional compensation chamber (14) is defined between the additional valve assembly (13) and one side of a slideable partition (10). A gas chamber (11) is defined at the other side of the slidable partition (10). The damper includes an additional chamber assembly (15) to retain all the advantages of a twin-tube damper while providing the single construction offered by a mono-tube damper. One end of the additional chamber assembly (15) is attached to the slidable piston chamber (5) or to said piston rod (6) at the compression side thereof and the other end of said additional chamber assembly (15) is terminated with the additional valve assembly (13).

摘要： A damper includes a housing bounding a primary chamber and a compensation chamber, the primary chamber including a first gas compartment and a control compartment that are separated by an expansion piston, the compensation chamber including a second gas compartment and an overflow compartment that are separated by a compensation piston. A piston rod has a first end slidably disposed within the control compartment. A first fluid path is in fluid communication with the overflow compartment so that when the expansion piston is in the first position, the expansion piston blocks fluid communication between the control compartment and the overflow compartment by way of the first fluid path and when the expansion piston is in the second position, the hydraulic fluid can freely flow from the control compartment to the overflow compartment by way of the first fluid path.

摘要： A vehicle height adjustment suspension device provides for both automatic and selective raising and lowering of a supported portion of a vehicle frame relative a ground surface, while also providing shock absorption. The device includes a suspension assembly for absorbing shocks mounted on a rotatable threaded screw connected to a motor and extending into the suspension assembly. The assembly may be extended and retracted on the screw by rotating the screw in first and second directions to raise and lower the supported portion while the shock absorber assembly simultaneously provides shock absorption capability.
