Title (EN) A TEMPERATURE ADAPTIVE FLUID DAMPING SYSTEM
(FR) SYSTÈME D'AMORTISSEMENT UTILISANT UN FLUIDE S'ADAPTANT À LA TEMPÉRATURE
Abstract: front page image
(EN)A temperature adaptive fluid damping system is provided. One embodiment of the temperature adaptive fluid damping system comprises two fluid chambers, a piston in fluid communication with the fluid chambers, and a fluid path between the fluid chambers. An elastomeric retaining element adjacent to the fluid path is constrained to deform substantially perpendicular to the fluid path, so that the retaining element is operable to vary the cross-sectional area of the fluid path inversely to a change in temperature.
(FR)L'invention concerne un système d'amortissement utilisant un fluide s'adaptant à la température. Dans une forme de réalisation, le système d'amortissement utilisant un fluide s'adaptant à la température comprend deux chambres de fluide, un piston en communication fluidique avec les chambres de fluide, et un circuit de fluide entre les chambres de fluide. Un élément de retenue élastomère, adjacent au circuit de fluide, est comprimé afin de se déformer de manière sensiblement perpendiculaire au circuit de fluide, de sorte que l'élément de retenue peut être utilisé pour faire varier la section transversale du circuit de fluide inversement à un changement de température.
