Abstract

L'invention concerne un ressort à gaz. Selon l'invention, il comprend un cylindre 10, un piston 14 coulissant dans le cylindre 10, une tige de piston 19 dont une extrémité est fixée au piston 14 et dont l'autre extrémité fait saillie en dehors du cylindre 10, une chambre à gaz 23 pouvant être comprimée, ou dilatée sur toute la course du piston, une autre chambre à gaz 11 disposée près de la première chambre et qui en est séparée par une paroi mobile 13, et une butée 24 pour restreindre le mouvement de la paroi mobile 13 vers la première chambre à gaz 23. L'invention s'applique notamment aux fermetures de portes ou fenêtres.
