Abstract

La présente invention concerne un amortisseur à fluide sous pression. Pour ledit amortisseur, une matière très élastique est utilisée pour le couvercle ou pour une partie de ce dernier et éventuellement pour l'enveloppe supportant ledit couvercle et entourant le cylindre. La surface latérale 4 du piston 3 est sphérique de façon que l'axe de la tige du piston puisse s'incliner par rapport à l'axe du cylindre en maintenant constant le diamètre du piston assurant l'étanchéité. Application aux véhicules à chenilles.
