Abstract

La présente invention concerne un dispositif à cône double qui produit une meilleure succion, une amplification de pression et un bruit réduit. Pour ce faire, est utilisée une géométrie continue destinée à deux sections frustroconiques du dispositif à cône double. En outre, une pluralité de trous sur le cône de sortie est utilisée pour aspirer la matière dans le dispositif. Ladite géométrie continue permet de déboucher sur un profil à flux stable qui engendre un bruit réduit et une meilleure amplification. Lesdits trous augmentent la force de succion, comme ils sont placés à proximité de l'orifice. D'autres améliorations sont réalisées par l'intermédiaire du choix de la fourchette appropriée d'angles du cône d'entrée et du cône de sortie.
