Title (EN) VENTILATING FAN AND A MECHANISM AND METHOD FOR OPENING AND CLOSING A SHUTTER OF THE FAN
(FR) VENTILATEUR DE VENTILATION ET MÉCANISME ET PROCÉDÉ D'OUVERTURE ET DE FERMETURE D'UN OBTURATEUR DU VENTILATEUR
Abstract:
(EN) A ventilator has a fan, a motor for rotating the fan and a mechanism for opening and closing a flow path for the air flow out of the ventilator. The motor creates torque during start of its operation that is utilized for both rotation of the fan and opening of the flow path.
(FR) La présente invention concerne un appareil de ventilation qui comporte un ventilateur, un moteur pour faire tourner le ventilateur et un mécanisme pour ouvrir et fermer un trajet d'écoulement pour l'écoulement d'air hors de l'appareil de ventilation. Le moteur génère un couple pendant le démarrage de son fonctionnement qui est utilisé pour la rotation du ventilateur et l'ouverture du trajet d'écoulement.
