Abstract

L'invention concerne un amortisseur rotatif qui, après qu'il soit terminé, peut être fixé à une charnière coulissante. Un amortisseur rotatif (3) comprend : un corps d'arbre (11) qui présente une première section d'arbre (11a), une seconde section d'arbre (11b), et une section de bride (11c) qui est disposée entre la première section d'arbre (11a) et la seconde section d'arbre (11b) et qui présente un diamètre externe plus grand que la première section d'arbre (11a) et la seconde section d'arbre (11b) ; et un composant amortisseur rotatif (12) dans lequel la première section d'arbre (11a) du corps d'arbre (11) est insérée et qui est disposé entre la section de bride (11c) du corps d'arbre (11) et une butée d'extraction (11a1) à l'extrémité de la première section d'arbre (11a) du corps d'arbre (11). La seconde section d'arbre (11b) du corps d'arbre (11) est insérée dans un trou de montage (8) dans une paroi latérale (5a) d'une charnière coulissante (2) de telle sorte que la seconde section d'arbre (11b) soit fixée à la charnière coulissante (2).
