Abstract

L'invention concerne un actionneur pour dispositif de commande hydraulique ou pneumatique comportant : - un corps (8) cylindrique, - un piston (10) coulissant dans le corps (8), - une tige de commande (12) mobile entre une position déployée et une position rétractée, un organe de butée (28) faisant saillie radialement de la tige de commande (12) et étant agencé pour coopérer avec une surface de butée (30) portée par le corps cylindrique (8), - une enveloppe (16) de protection entourant la tige de commande (12) et comportant successivement : ○ une première extrémité (17) fixée sur le corps (8), ○ une portion rigide (21) à l'intérieur de laquelle l'organe de butée (28) se déplace, ○ une portion déformable (22) présentant un état compressé et un état développé; et ○ une seconde extrémité (19) fixée sur la tige de commande (12), le piston (10) définissant avec le corps (8) une troisième chambre (39) à volume variable dont le volume varie de manière à recevoir ou fournir du fluide respectivement en provenance ou vers la portion déformable (22).The invention relates to an actuator for a hydraulic or pneumatic control device comprising: - a cylindrical body (8), - a piston (10) sliding in the body (8), - a control rod (12) movable between a deployed position and a retracted position, a stop member (28) projecting radially from the control rod (12) and being arranged to cooperate with a stop surface (30) carried by the cylindrical body (8), - a casing (16 ) protection surrounding the control rod (12) and comprising successively: ○ a first end (17) fixed to the body (8), ○ a rigid portion (21) inside which the stop member (28 ) moves, ○ a deformable portion (22) having a compressed state and a developed state; and ○ a second end (19) fixed to the control rod (12), the piston (10) defining with the body (8) a third chamber (39) with variable volume, the volume of which varies so as to receive or supply fluid respectively coming from or towards the deformable portion (22).
