Abstract

L'invention concerne un ressort à gaz à positions d'arrêt multiples, comportant un deuxième ensemble piston d'arrêt outre un ensemble piston doseur, raccordés à la tige du ressort à gaz. L'ensemble piston d'arrêt est de préférence espacé axialement de l'ensemble piston doseur. L'ensemble piston d'arrêt peut être utilisé pour stopper le mouvement de la tige dans un sens, en un ou plusieurs points présélectionnés sur la course normale de la tige, et/ou pour induire le mouvement de l'axe dans ledit sens et le ralentir par incréments avant qu'il soit stoppé de manière amortie, lorsqu'il approche de la fin de sa course. La tige peut se déplacer dans l'autre sens sans entrave ou peut s'arrêter dans les deux sens.
