Abstract

L'invention porte sur une vis de rattrapage qui peut être empêchée de tourner et de se déplacer dans la direction de poussée lorsqu'une charge est appliquée à la vis de rattrapage dans la direction de poussée par rotation d'une came. Le rattrapeur de jeu (1) comprend un boîtier tubulaire (12) qui est introduit dans un trou de réception (11) débouchant sur la surface supérieure d'une culasse (2), la périphérie externe de la vis de rattrapage (15) comportant un filetage mâle (14) vissé sur un filetage femelle (13) formé sur la périphérie interne du boîtier (12), et un ressort de rappel (17) pour solliciter la vis de rattrapage (15) dans une direction telle que la vis de rattrapage se projette vers le haut à partir du boîtier (12) et supporte un bras (7) par l'extrémité de projection (19) de la vis de rattrapage (15) se projetant à partir du boîtier (12). Dans le rattrapeur de jeu (1), la surface de l'extrémité de projection (19) de la vis de rattrapage (15) est réalisée en un matériau qui ne réagit avec un additif organique d'huile contenant du molybdène.
