Abstract
L'embrayage comporte un organe menant 30 fixé à un arbre d'entraînement 0, un organe mené 18 coaxial monté à rotation libre sur l'arbre 0 et un ressort bistable 38 en forme de disque qui, dans une de ses positions stables, accouple entre eux les organes menant et mené et, dans l'autre, les désaccouple; le ressort 38, dans sa position d'accouplement, établit un accouplement à glissement qui permet à l'organe menant de tourner sans entraîner l'organe mené lorsq'une force de retenue prédéterminée est appliquée à ce dernier. Application aux ventilateurs à tête stationnaire produisant un courant d'air giratoire à l'aide d'une grille rotative.
