Abstract

La présente invention concerne un actionneur (10), comprenant : un boîtier (100) ; une tige de poussée (200) logée partiellement à l'intérieur du boîtier (100) ; un mécanisme d'entraînement (300) relié à la tige de poussée (200) ; un mécanisme de support (400) logé à l'intérieur du boîtier (100) ; et un premier interrupteur de fin de course (500) et un second interrupteur de fin de course (600) espacés l'un de l'autre et logés à l'intérieur du boîtier (100) au moyen du mécanisme de support (400). Une position de liaison du premier interrupteur de fin de course (500) et/ou du second interrupteur de fin de course (600) peut être changée par rapport au mécanisme de support (400) le long d'une direction axiale de la tige de poussée (200), de sorte que le second interrupteur de fin de course (600) peut être ajusté par rapport au premier interrupteur de fin de course (500) le long de la direction axiale de la tige de poussée (200), de façon à ajuster la distance entre le premier interrupteur de fin de course (500) et le second interrupteur de fin de course (600) ; et, en conséquence, changer la plage de mouvement pour un mouvement de va-et-vient de la tige de poussée (200) afin de réaliser un ajustement de la longueur de course de l'actionneur (10). L'invention est très adaptable et satisfait une exigence utilisateur d'actionneurs ayant différentes longueurs de course.
