Abstract

L'invention concerne un amortisseur de charnière fixé à une charnière de porte de meuble afin d'absorber un gros choc même si l'amortisseur est de petite taille. L'amortisseur de charnière absorbe un gros choc même s'il est de petite taille en formant des premier et second joints à l'intérieur d'un joint d'huile d'un amortisseur de charnière traditionnel afin d'empêcher l'air de passer et formant une nervure transversale sur un piston. L'amortisseur de charnière amortit un gros choc même s'il est de petite taille et est formé de sorte qu'il n'y ait aucune influence sur la taille de la charnière. La taille de l'amortisseur de charnière correspond à celle d'une vis pour fixer la charnière de sorte que l'amortisseur ne soit pas exposé à l'extérieur.
