Abstract
Le mécanisme d'échappement à force constante, notamment pour mouvement d'horlogerie comprenant un balancier-spiral et un mobile d'échappement relié à un barillet par un rouage de finissage comporte un ressort auxiliaire de force constante (11). Il comporte une ancre d'impulsion (8) coopérant d'une part avec le mobile d'échappement (1) et d'autre part avec des organes de commande solidaires de l'arbre du balancier-spiral. Le ressort auxiliaire de force constante (11) est fixé par l'une de ses extrémités sur une partie du bâti du mouvement et par son autre extrémité à l'ancre d'impulsion (8). The constant force escapement mechanism, in particular for a clockwork movement comprising a balance-spring and an escapement mobile connected to a barrel by a finishing train, comprises an auxiliary spring of constant force (11). It comprises a pulse anchor (8) cooperating on the one hand with the escape wheel (1) and on the other hand with integral control members of the balance spring shaft. The auxiliary spring of constant force (11) is fixed at one end to a part of the movement frame and at its other end to the pulse anchor (8).
