English[en]
A gas spring apparatus includes first and second cylinders, with first and second pistons each capable of axial displacement being disposed inside a fluid-filled inner space of the cylinders, the first piston dividing the first cylinder into two sub-spaces, the second piston dividing the second cylinder into two cylindrical chambers, first and second piston rods, each of which is connected to the corresponding piston being mounted in a sliding and sealing fashion in one end wall, a plurality of valves selectively communicating among two sub-spaces and two cylindrical chambers as to impart an additional depression movement to the piston rod of the gas spring, first and second pistons can be caused to move upwards and back to an initial position of each of the first and second pistons after a predetermined delay.
French[fr]
Une pluralité de soupapes permettent de mettre en communication d'une manière sélective les deux sous-espaces et les deux chambres cylindriques de manière à conférer un mouvement additionnel d'enfoncement à la tige de piston du ressort à gaz. Les premier et second pistons peuvent être amenés à se déplacer vers le haut et à revenir à leur position initiale respective, après un retard prédéterminé.
