Abstract

Dispositif d'amortissement constitué d'un manchon qui glisse sur la tige du vérin et porte un piston se déplaçant dans une chambre d'amortissement. Le vérin comporte un piston 12 se déplaçant dans un cylindre 10 et portant une tige 14. Sur cette tige 14 glisse un manchon 24 portant un piston 25 qui se déplace dans la chambre d'amortissement 26 flanquée de part et d'autre de deux chambres annulaires 30, 32 et de soupapes antiretour 33, 34. La liaison entre la chambre 26 et les chambres 30, 32, par l'intermédiaire des perçages 37, 38, peut être plus ou moins étranglée par les soupapes 39, 40.Damping device consisting of a sleeve which slides on the cylinder rod and carries a piston moving in a damping chamber. The jack comprises a piston 12 moving in a cylinder 10 and carrying a rod 14. On this rod 14 slides a sleeve 24 carrying a piston 25 which moves in the damping chamber 26 flanked on either side by two chambers. annular 30, 32 and non-return valves 33, 34. The connection between the chamber 26 and the chambers 30, 32, through the bores 37, 38, can be more or less constricted by the valves 39, 40.
