Les figures ne sont qu'un exemple, on peut par exemple modifier la roue d'échappement pour qu'elle soit à deux niveaux et l'ancre à un seul niveau (excepté le dard).The figures are only an example, for example, the escape wheel can be modified so that it is two-level and the anchor at one level (except the stinger).
En somme, l'invention réalise deux échappements en un.In sum, the invention realizes two escapements in one.
Ces deux échappements peuvent être soit mécaniques, magnétiques, électrostatiques, ou autre.These two exhausts can be either mechanical, magnetic, electrostatic, or other.
Ces deux échappements ne sont pas en concurrence, mais leurs plages de fonctionnement permettent que le deuxième échappement prenne le relais lorsque le premier sort de sa plage de couple admissible.These two exhausts are not in competition, but their operating ranges allow the second exhaust to take over when the first one leaves its permissible torque range.
En cas de couple trop élevé, le second échappement évite un décrochage, et ne bloque pas le système.If the torque is too high, the second exhaust avoids a stall, and does not block the system.
L'échappement « principal » magnétique, par exemple, a un meilleur rendement car il fonctionne sans frottement et est, par exemple, à « force constante ». il est, encore, silencieux, et présente de bonnes propriétés chronométriques. Il peut par contre présenter un problème de sécurité, et de décrochage en cas de choc ou de surcouple au niveau du mobile d'échappement. Le deuxième échappement complémentaire, de type mécanique dans une variante particulière, robuste mais de rendement plus faible et difficilement à force constante, prend justement le relais lorsque le couple est extrême pour le premier échappement. Les deux échappements combinés sont donc complémentaires et présentent globalement de meilleures propriétés.The "main" magnetic exhaust, for example, has a better performance because it operates without friction and is, for example, "constant force". it is still silent and has good chronometric properties. It may however present a safety problem, and stall in case of shock or over-torque at the mobile exhaust. The second complementary exhaust, of mechanical type in a particular variant, robust but of lower efficiency and hardly constant force, just takes over when the torque is extreme for the first exhaust. The two exhausts combined are therefore complementary and generally have better properties.
