Hydraulic braking system for loads subjected to impacts and vibrations
Description
This invention concerns a hydraulic braking system for loads subjected to impacts and vibrations. These double acting telescopic type hydraulic braking systems possess significant drawbacks linked to possibly important hydraulic leaks due to (a) the use of many dynamic seals in such appliances and (b) the effects of the environment of the system on these seals, particularly when employed in nuclear power stations where the seals reach significant temperatures and are subjected to radiation. Under this invention a remedy is suggested to such drawbacks by integrating means to offset automatically the leaks and the accumulation of hydraulic fluid expansions, as well as facilities to show if such leaks have occurred

La presente invention a pour objet un dispositif hydraulique de freinage pour charge soumise a des chocs et vibrations. Ces dispositifs hydrauliques de freinage, du type telescopique, a double effet, presentent des inconvenients importants tenant a la possibilite de fuites hydrauliques non negligeables compte-tenu, d'une part, de l'emploi dans ces dispositifs, d'une pluralite de joints d'etancheite dynamiques, et, d'autre part, des effets de l'environnement du dispositif sur ces joints, en particulier dans le cadre d'application dans les centrales nucleaires, ou les joints sont portes a des temperatures importantes et sont exposees a des radiations. Par la presente invention, on se propose de remedier a ces inconvenients en integrant des moyens qui permettent la compensation automatique des fuites, et l'accumulation des dilatations du fluide hydraulique, ainsi que des moyens indiquant si des fuites se sont produitesAdditional details
