FIELD: physics.SUBSTANCE: escapement wheel includes an impulse gear wheel and a separating gear wheel, which synchronously rotate about an axis. The separating gear wheel includes sliding pinions, each having a separating cog which radially moves relative to said axis and is returned to the balance position by a first return means, and a locking cog returned in a first radial direction to the support by a second return means. Said impulse cog includes a drive means designed for interaction, when said impulse cog moves in a second radial direction opposite to said first direction, with the drive means of said locking cog.EFFECT: actuating said locking cog in a second direction and, when said impulse cog moves in the first direction, maintaining distance from said interlinked drive means without actuating said locking cog.22 cl, 10 dwg |
