Abstract

a. Amortisseur télescopique, notamment pour véhicules automobiles. b. Amortisseur caractérisé en ce qu'une bague d'amortissement entourant la tige de piston est prévue entre la bague de butée et le couvercle, cette bague d'amortissement s'appuyant, au-delà d'une course de sortie déterminée, élastiquement sur le cylindre par l'intermédiaire d'un ressort d'appui hélicoïdal et constituant au moyen de la bague de butée un piston d'amortissement supplémentaire en cas de déplacement axial. c. L'invention s'applique, notamment, à l'industrie automobileat. Telescopic shock absorber, in particular for motor vehicles. b. Shock absorber characterized in that a damping ring surrounding the piston rod is provided between the stop ring and the cover, this damping ring resting, beyond a determined output stroke, elastically on the cylinder by means of a helical support spring and constituting by means of the stop ring an additional damping piston in the event of axial displacement. vs. The invention applies, in particular, to the automotive industry
