Abstract

La présente invention concerne une buse de génération de mousse à rotation automatique. La buse de génération de mousse comprend un corps de buse, des tuyaux de prolongement, et une pluralité d'aubes. Le corps de buse possède des passages d'entrée de solution de mousse. La tête de buse possède une partie de retenue de corps de buse qui est insérée dans l'extrémité avant du corps de buse. La tête de buse est configurée de sorte qu'une pluralité de passages de décharge de solution de mousse qui communiquent avec la partie de retenue de corps de buse soit formée dans celle-ci et soit prévue afin de tourner par rapport au corps de buse. Les tuyaux de prolongement sont pourvus d'orifices de pulvérisation qui possèdent des directions de pulvérisation, qui sont réglées de sorte que la tête de buse soit tournée par la réaction à la pulvérisation de la solution de mousse. Les aubes sont prévues de façon radiale sur la tête de buse.
