ABSTRACT:
A control device sensitive to speeds exceeding a pre-determined rotation speed, characterized in that it comprises a mobile locking ring for a driving organ, resiliently returned to the locking position, a sleeve freely rotating inside said ring at a speed linked to the speed to be controlled, and comprising at least a peripheral fly-weight, returned to its rest position by a calibrated spring, and mounted in such manner as, under the action of the centrifugal force created by said pre-determined rotation speed and against the action of the return spring, to engage with the inner surface of the ring, in order to cause it to leave its locking position.
