Abstract

La présente invention se rapporte à un ventilateur. Selon l'invention, un volet pivotable 4 est disposé sur la sortie d'air 7 de l'enveloppe 1 du ventilateur. Dans le cas du sens de rotation r, la pression F1 créée pousse le volet 4 vers la position d'arrêt 5. Dans le cas du sens de rotation p, le volet 4 est poussé vers la position d'arrêt 6. L'invention s'applique dans le domaine des machines soufflantes.
