Abstract

Selon l'invention, un ensemble palier peut être fixé de manière amovible relativement à un boîtier extérieur d'un dispositif de commande rotatif sans utiliser de pression de fluide. Un exemple de procédé comprend insérer l'ensemble palier dans un boîtier externe pour déplacer vers l'extérieur un élément d'engagement de verrou. L'élément d'engagement est sollicité vers l'intérieur sans pression de fluide, par exemple par un ressort. L'ensemble est déplacé vers une position active dans le boîtier externe dans laquelle l'élément d'engagement sollicité vers l'intérieur se déplace vers l'intérieur pour venir en prise avec un évidement sur l'ensemble palier. La pression de fluide peut ensuite être utilisée une fois que l'ensemble palier est verrouillé pour éventuellement aider à maintenir l'élément d'engagement dans l'évidement ou pour dégager l'élément d'engagement de l'évidement pour déverrouiller l'ensemble palier.
