La présente invention concerne un dispositif amortisseur de porte coulissante comprenant : un premier corps fixe fixé/accouplé à l'intérieur d'un cadre supérieur de porte ; un second corps fixe fixé/accouplé à l'intérieur du cadre supérieur de porte tout en étant espacé du premier corps fixe ; un élément de support installé entre le premier corps fixe et le second corps fixe ; un cylindre installé entre le premier corps fixe et le second corps fixe tout en étant supporté par l'élément de support ; un dispositif de suspension rotatif accouplé à l'extrémité avant d'une tige du cylindre et conçu de façon à pouvoir se déplacer le long de l'élément de support ; un corps de liaison pivotant monté sur le côté supérieur du corps de porte de telle sorte que le corps de porte se déplace le long du cadre supérieur de porte, le corps de liaison pivotant ayant une saillie d'impact formée au niveau d'un point sur celui-ci de telle sorte que, lors de la mise en contact du dispositif de suspension rotatif, celui-ci applique un impact au dispositif de suspension rotatif, déplaçant ainsi le dispositif de suspension rotatif le long de l'élément de support ; un ressort amortisseur conçu de telle sorte que, lorsque la saillie d'impact applique un impact au dispositif de suspension rotatif pendant la fermeture de la porte, celui-ci est déformé par l'impact provenant de la saillie d'impact, ce qui permet d'amortir l'impact provenant de la saillie d'impact ; et un ressort de fermeture de porte conçu de telle sorte que, lorsque la saillie d'impact applique un impact sur le dispositif de suspension rotatif, celui-ci entre en contact avec le corps de porte et le positionne dans la position de fermeture de porte.
