Abstract

L'invention concerne un procédé pour remplir la cavité de pression d'un dispositif hydraulique de ressort et d'amortissement, et un dispositif ainsi rempli. Procédé caractérisé en ce que dans un trou fileté 1b prévu dans le corps 1 du dispositif et menant à la cavité de pression la, on introduit une tige de remplissage 2 munie d'un perçage traversant 2a et pénétrant par son corps dans la cavite de pression la; puis on introduit à travers le perçage traversant 2a l'agent de pression 3 jusqu'à ce que la cavité la soit remplie, après avoir retiré la tige de remplissage 2, on introduit alors dans la cavité la, à travers le trou fileté 1b, une capsule à paroi mince, de dimensions correspondant au corps de la tige 2, qui contient l'agent de poussée à l'état liquide ou solide, et enfin on bouche hermétiquement le trou fileté 1b du corps 1 au moyen d'une vis. L'invention est plus particulièrement applicable à la construction de tampons de chemin de fer.The invention relates to a method for filling the pressure cavity of a hydraulic spring and damping device, and a device thereby filled. Method characterized in that in a threaded hole 1b provided in the body 1 of the device and leading to the pressure cavity 1a, a filling rod 2 provided with a through hole 2a and penetrating through its body into the pressure cavity is introduced. the; then the pressure agent 3 is introduced through the through hole 2a until the cavity 1a is filled, after removing the filling rod 2, then introduced into the cavity 1a, through the threaded hole 1b, a thin-walled capsule, of dimensions corresponding to the body of the rod 2, which contains the pushing agent in the liquid or solid state, and finally the threaded hole 1b of the body 1 is hermetically sealed by means of a screw. The invention is more particularly applicable to the construction of railway buffers.
