Problems solved by technology

The displacement of the outer end of the hairspring is thus bidirectional and may be zero throughout the period of the oscillator, which undoubtedly causes a reduction in the performance and stability of the balance wheel's amplitude
In addition, this type of device cannot act on the hairspring at the moment when the balance reaches the end of its oscillations
This type of scheme thus leads to significant isochronism drawbacks

Embodiment Construction

[0036] In each embodiment of the invention, it is proposed to couple the first vibrator with a second subsystem, which preferably comprises a second vibrator, and whose vibrators suitably adjust their frequency, or The frequency is suitably adjusted so as to act on one and / or the other of the two vibrators at the appropriate instant. This type of regulating system thus enables the realization of a substantially isochronous regulating device, the vibration of which is maintained by a change in potential energy. The action on the vibrator is the action where the potential energy changes.

[0037] The regulating system is capable of maintaining the balance spring through changes in potential energy and must therefore satisfy two a priori contradictory conditions, namely, it must be able to generate shocks sufficient to produce a displacement of the balance spring, in particular of one end of the balance spring (for example the inner or outer end of the balance spring ) and the i...

Abstract

A regulating system (110) for a horology movement (12) comprising a first sub-system (11) including: a first oscillator (O111) which includes a first balance (B111) and a first balance spring (S111); a first element (M111) for displacement of the first balance spring (S111); and a first element (A111) for activation of the first displacement element (M111), at an instant, or substantially at an instant, when the speed of the first balance (B111) is zero.

Description

technical field [0001] The present invention relates to an adjustment system or a regulator for a watch movement, or to an adjustment system or a regulator for a watch movement. The invention also relates to a timepiece movement comprising an adjustment system of this type. The invention also relates to a horological piece, in particular a watch, comprising a movement or regulating system of this type. Background technique [0002] The vibration of the regulating mechanism is usually maintained by the shock of the escapement. These shocks act directly or indirectly on the hairspring assembly, so as to provide it with kinetic energy. [0003] This type of maintenance of the balance spring vibration theoretically guarantees the isochronism of the timepiece, assuming that the performance of the escapement is strictly identical at each stroke. However, this condition is difficult to fully satisfy as a result of disturbances of the escapement or changes in the drive force prod...
