Abstract

L'invention concerne un dispositif de descente qui se caractérise en ce qu'une partie gravité (1) est chargée par le biais d'une partie chargement (2); la partie chargement (2) est reliée et fixée à une corde (3) qui est enroulée autour d'un cylindre d'enroulement (4); ledit cylindre d'enroulement (4) est fixé sur un arbre rotatif (5), qui est fixé sur un support (8) par le biais de sièges d'axes (6.1, 6.2); une partie rotative (5.2) est installée sur l'arbre rotatif (5); un arbre à vilebrequin (5.1), monté sur la partie rotative (5.2), est relié à un piston de limitation de vitesse (7) par le biais d'une tige de piston (7.1); le piston de limitation de vitesse (7) est fixé sur le support (8); l'invention concerne également un siège de support (9), qui est enroulé en feuillard autour de l'extérieur de la partie rotative (5.2). Lorsque ladite partie rotative (5.2) tourne, la surface interne (9.1) du siège de support coopère avec la surface externe (5.2.1) de la partie rotative (5.2) et le siège de support (9) agit comme support de la partie rotative (5.2). Il est avantageux que la structure de contrainte de l'arbre à vilebrequin soit plus rationnelle, de façon à assurer une utilisation en toute sécurité.
