Abstract
Mechanical timepiece movement, including at least one energy storage means fed at the input by a ratchet driven by one winding mechanism and at the output powering a going train. The movement includes first energy take-up means connected to at least one wheel set of this going train by at least a first elastic connection, this first energy take-up means cooperating with at least one wheel set driving this ratchet, in mesh with this ratchet for powering this energy storage means by reinjecting part of the energy taken up by this energy take-up means, this wheel set driving this ratchet being uncouplable under the action of at least one uncoupling mechanism active during the operation of this winding mechanism.
Claims15
A mechanical timepiece movement, including at least one energy storage means fed at an input by a ratchet driven by at least one winding mechanism and at an output powering a going train, wherein the mechanism includes first energy take-up means connected to at least one wheel set of said going train by at least a first elastic connection forming an uncoupling mechanism, said first energy take-up means taking up energy from said going train which is powered by said energy storage means, and said first energy take-up means cooperating with at least one wheel set driving said ratchet, said drive wheel set is in mesh with said ratchet to feed said energy storage means by reinjecting part of the energy taken up by said energy take-up means.
