MECHANICAL CLOCK MECHANISM WITH MAGNETIC ESCAPEMENT Russian patent published in 2018 - IPC G04C5/00 

FIELD: clocks and other time meters.

SUBSTANCE: mechanical clock mechanism (2) comprising resonator (10), escapement linked to the resonator, and display (8) of at least one item of time information, wherein display is driven by mechanical drive device (4) via counter wheel train (6), the work rate of which is set by the escapement, wherein at least said resonator is housed in chamber (14), in which a reduced pressure in relation to atmospheric pressure prevails. Escapement is magnetic escapement (12), including an escape wheel coupled directly or indirectly to the resonator via a magnetic coupling system, wherein the magnetic coupling system is formed so that a non-magnetic wall of the chamber runs through the magnetic escapement, wherein a first part of the escapement is located inside the chamber whereas a second part of the escapement is located outside the chamber.

EFFECT: mechanical clock mechanism with a magnetic escapement is proposed.
