Abstract

Une réalisation d'actionneur axial comprend deux enceintes cylindriques, concentriques, intégrées (1, 3) d'une hauteur différentielle. Très éloigné de la valve, un disque (4) de piston divise l'espace (A et B) entre les deux enceintes. Une cavité (18) ou une série de cavités cylindriques (18a) encerclent l'enceinte interne de façon à loger des ressorts de compression (17), et des bras d'engrenage à crémaillère (4B), faisant saillie vers la valve depuis le rebord du disque (4) du piston, viennent en contact avec des pignons composés (G1, G2, G3, G4). Les extrémités opposées des pignons composés viennent en contact avec la roue conique principale (2) la plus proche de la valve. Lorsque le piston (4) est actionné par un actionneur, le moyeu (23) de la roue conique (2) actionne l'arbre (A) de la valve quart de tour.
