Abstract
L'invention concerne un ressort pneumatique, en particulier pour véhicules, comportant une capacité élastique fermée et deux surfaces élastiques efficaces de grandeur différente, alimentées en pression dans des sens opposés, travaillant dans des sens opposés et variant en étendue l'une par rapport à l'autre en fonction de la course du ressort, la capacité élastique étant constituée par deux diaphragmes délimitant une chambre commune dont les surfaces efficaces orientées dans des sens opposés prennent appui sur des pistons raccordés l'un à l'autre. Il est caractérisé par le fait que les deux pistons du ressort 5, 6 sont montés élastiquement l'un sur l'autre de façon telle que leur distance axiale varie de façon limitée en fonction de la pression régnant dans la chambre élastique. Application à tout véhicule automobile.
