Abstract

Ce régulateur est du type de ceux comportant des pales directrices 16 dont les positions respectives sont réglables simultanément par un mecanisme commun 14 et sont montées sur pivots 22, 23 par leurs extrémités radiales, à l'extérieur, sur une paroi enveloppante 12, à l'intérieur sur un moyeu 21. Dans le regulateur selon l'invention, le mécanisme commun 14 pour le réglage simultané de la position des pales 16 est placé dans la zone du moyeu 21. On peut ainsi conformer le régulateur de façon qu'il tienne entièrement dans l'ouïe d'un ventilateur et soit traversé par l'arbre de celui-ci.
