Abstract

------ Actionneur à double commande électrique et pneumatique L’invention concerne un actionneur (1) comprenant une chambre de translation (3), un déclencheur (15), l’actionneur comprenant un premier élément (22) et un deuxième élément (35), un électroaimant (31) commandé électriquement par des moyens de commande de l’électroaimant (13), disposé entre les deux éléments (22, 35), un élément de rappel élastique (39) disposé dans la chambre de translation (3) pour, dans la position désactivée de l’électroaimant (31), déplacer le deuxième élément (35) pour placer le déclencheur (15) dans sa position de déclenchement, une surpression étant créée par des moyens de commande pneumatique pour déplacer le premier élément (22), afin de placer le déclencheur (15) dans sa position de déclenchement indépendamment de l’état de l’électroaimant (31), et une butée (7) dans la chambre de translation (3) pour limiter la course du déclencheur (15) dans la chambre de translation (3). Figure à publier avec l’abrégé : Figure 1------ Double electric and pneumatic actuator The invention relates to an actuator (1) comprising a translation chamber (3), a trigger (15), the actuator comprising: a first element (22) and a second element (35), an electromagnet (31) electrically controlled by means for controlling the electromagnet (13), disposed between the two elements (22, 35), an elastic return element (39) disposed in the translation chamber (3) to, in the deactivated position of the electromagnet (31), move the second element (35) to place the trigger (15) in its trigger position, an overpressure being created by pneumatic control means to move the first element (22), in order to place the trigger (15) in its triggering position independently of the state of the electromagnet (31), and a stop (7) in the translation chamber (3) to limit the travel of the trigger (15) in the translation chamber (3).
