Abstract

Cet appareil à tension, de petit diamètre, peut s'adapter à un moteur de dimensions réduites. Dans cet appareil (A1), un élément d'arbre (3), faisant partie d'une paire d'éléments d'arbre (3, 4) vissés ensemble, est sollicité pour entrer en rotation par un ressort de torsion (5) et propulsé hors d'un logement (29) par la rotation du second élément d'arbre (4) restreinte par un appui (6). Celui-ci se compose d'une pièce de guidage (13) et d'une pièce de fixation (14). La pièce de guidage (13) se déploie le long du sens de propulsion, ce qui lui donne une forme sensiblement tubulaire. Le second élément d'arbre dont la rotation est restreinte, pénètre dans la pièce de guidage (13) qui guide son déplacement. La pièce de fixation (14) est montée à demeure sur la base de la pièce de guidage (13) et fixée, de telle sorte que sa rotation soit restreinte, au sommet du logement (2).
