Abstract
A spring-damping device operating with a pressurized gas in which sudden movements caused by a severe drop in pressure are avoided or limited. A variable volume chamber, which is usually in a state where it permits relative movement of a rod in relation to an enclosure, distorts during a rapid depressurization in the enclosure, until it opposes these movements, due to a valve which maintains its internal pressure near to the initial level.
