Abstract

L'invention concerne un dispositif d'éjection d'un milieu d'extinction (13) comportant au moins une ouverture d'éjection (22). L'ouverture d'éjection (22) est caractérisée en ce que le milieu d'extinction (13) adopte une forme de jet si plate qu'il ne peut s'y former aucun tourbillon susceptible d'émettre des ondes sonores d'une longueur d'onde du spectre acoustique perceptible par l'oreille humaine. Ceci est garanti par la géométrie de l'ouverture d'éjection (22).
