Abstract
L'invention concerne un dispositif de commande de fluide (20) à niveau sonore réduit. Ledit dispositif est une vanne de type buse présentant une partie convergente (A) et une partie divergente (B) entre lesquelles se trouve un étranglement (38). La partie divergente (B) sert de diffuseur et peut être conique ou présenter une faible courbure. Dans chaque cas, l'angle de diffusion est inférieur à 20 DEG de sorte que la turbulence du fluide s'écoulant à travers la vanne est réduite, et une couche limite est maintenue entre le fluide et une surface interne du dispositif de commande de fluide (20). L'invention concerne également un système de commande utilisant un tel dispositif de commande de fluide. Ce dispositif peut être utilisé soit dans une conduite d'alimentation soit dans une conduite d'évacuation.
