Abstract
L'invention concerne un actionneur télescopique comportant un cylindre (1) ayant une extrémité fermée (2) et une extrémité ouverte (3) pour le passage d'une tige creuse (4) montée à coulissement axial dans le cylindre. L'actionneur comporte un support central (10) qui s'étend depuis l'extrémité fermée du cylindre à l'intérieur de la tige et qui porte des obstacles (15) mobiles radialement entre une position escamotée laissant libre un coulissement de la tige et une position en saillie dans laquelle les obstacles sont engagés dans une gorge (9) de la tige pour verrouiller axialement la tige relativement au cylindre, les flancs des obstacles et de la gorge étant conformés pour empêcher tout retrait des obstacles par déplacement de la tige, les obstacles étant disposés à l'extrémité de lames élastiques (14) s'étendant longitudinalement et agencées pour rappeler les obstacles de la position escamotée à la position en saillie, le support central portant des moyens commandés (20) de flexion des lames pour provoquer le retrait des obstacles vers la position escamotée.
