Abstract
An oleo-pneumatic damper comprises a hollow rod slidable within a cylinder, and a low-pressure gas chamber defined within the cylinder adjacent to a first variable volume of hydraulic fluid, which volume is essentially provided in the hollow rod. A second variable volume of hydraulic fluid in the rod is separated from the first fluid volume by a valve device, and a separating piston separates the second fluid volume from a high-pressure gas chamber, also in the hollow rod. A spring in the first fluid volume urges the hollow rod into the cylinder, thereby to form an anti-threshold spring to reduce the threshold or minimum loading on the damper, at which the damper will commence a compression stroke movement for damping purposes.
