Abstract
The clutch comprises at least one weight (11), and preferably two weights, disposed in a bell element (3) radially of the output shaft (2) of the motor (1), subjected to the action of an elastic element (21) for biasing the weight to a de-clutched position at rest, and capable of being driven by centrifugal force developed by the rotation of the shaft (2) of the motor (1) to a clutching position in which the weight engages the bell element (3). The bell element (3) is provided internally with a stressed spring (24) which frictionally bears against the inner wall of the bell element and is provided with at least one clutch dog (24a), and preferably two clutch dogs, cooperative with the weight or weights (11). The spring (24) limits the torque and permits avoiding rebounds in the event of a sudden stoppage of the bell element (3) at the end of the travel of the actuator.
