Abstract

Le mécanisme de compteur instantané comprend une came escargot (3) entraînée en rotation par un axe (4) qui porte une roue de chronographe (6); une bascule (1) de compteur, soumise à l'action d'un ressort, comportant un palpeur (2) prenant appui sur la périphérie de la came escargot (3) et un cliquet (8) coopérant sous l'action d'un ressort de cliquet (9) avec la denture en dent de loup d'une roue de compteur. La came escargot (3) comporte une fente (20), s'étendant sur une portion d'arc (c) comprise entre 30° et 90°, séparant du corps central de la came escargot une partie terminale (21) dont l'extrémité forme la partie la plus haute (H) de la came escargot (3); le palpeur (2) de la bascule (1) comportant une fraisure (22) donnant passage à ladite partie terminale (21) de la came escargot (3).
