Abstract
Un assemblage démerillon pour un actionneur comprend : une tige définissant une prise et une surface arquée au plancher de la prise; un capuchon dimensionné pour être accueilli dans la prise définissant une surface arquée convexe dimensionnée pour correspondre à la surface arquée du plancher de la prise; une première surface augmentée définie par la tige au moins en partie par des parties latérales de la prise offrant une profondeur à la prise; une deuxième surface augmentée définie par le capuchon offrant une longueur allongée au capuchon pour lui permettre de sétendre hors de la prise lorsque la surface arquée convexe du capuchon entre en contact avec la surface arquée du plancher de la prise; et un ensemble de vérin en raccord fonctionnel avec un piston et le capuchon pour leur permettre de se déplacer sur le plan axial dun axe longitudinal de lensemble de vérin pour se déplacer vers lintérieur et lextérieur dudit ensemble.
