Title (EN) LINEAR ACTUATOR, AS WELL AS CLOSING / OPENING SYSTEM THAT INCLUDES SUCH ACTUATOR
(FR) ACTIONNEUR LINÉAIRE, ET SYSTÈME DE FERMETURE/OUVERTURE COMPRENANT UN TEL ACTIONNEUR
Abstract:
(EN) A linear actuator comprising at least one jacket (10) defining an axis (X) and at least one rod (20) having an end cylinder (21) tightly slidable in the at least one jacket (10) and an opposite end (22) sliding between a rest position and a working position. The end cylinder (21) divides the at least one jacket (10) into at least one first and second variable volume compartments (18', 18") fluidically independent to each other, one of them (18', 18") being fluidically insulated and under vacuum, the other (18', 18") being fluidically communicating with the outside environment. Upon the passage of the opposite end (22) from the rest position to the working position one of the compartments (18', 18") passes from a minimum volume to a maximum volume, in order to suck the at least one rod (20) automatically recalling the opposite end (22) from the working position to the rest position.
(FR) L'invention concerne un actionneur linéaire comprenant au moins une enveloppe (10) définissant un axe (X) et au moins une tige (20) ayant un cylindre d'extrémité (21) pouvant coulisser de manière serrée dans ladite ou lesdites enveloppes (10) et une extrémité opposée (22) coulissant entre une position de repos et une position de travail. Le cylindre d'extrémité (21) divise ladite ou lesdites enveloppes (10) en au moins un premier et un second compartiments à volume variable (18', 18") fluidiquement indépendants l'un de l'autre, l'un d'entre eux (18', 18") étant isolé fluidiquement et sous vide, l'autre (18', 18") étant en communication fluidique avec l'environnement extérieur. Lors du passage de la position de repos à la position de travail de l'extrémité opposée (22), l'un des compartiments (18', 18") passe d'un volume minimal à un volume maximal, afin d'aspirer ladite ou lesdites tiges (20) rappelant automatiquement l'extrémité opposée (22) de la position de travail à la position de repos.
