the closing spring (9) by means of the reducing gears (13) of the inertia fly-
wheel (8) and the chain (15).

At the full stroke, the gear (19) is at the no tooth sector of the inertia flywheel
(8) and the reducing gears (13) can decelerate without causing strain on the
closing latch (14).
NOTE : During the loading of the closing spring, the supplying circuit
of the closing coil is cut to avoid an untimely closing operation.
