Abstract

Passage tournant pour deux milieux comprenant un passage commandé par pression L'invention concerne un dispositif de lavage de jantes et pneus pour le passage de deux milieux à travers une tête de buse (2) rotative. Le passage de milieux est commandé par pression et comprend les caractéristiques suivantes : • - une tête de buse (2) composée de deux canaux (3, 4)s'étendant perpendiculairement l'un par rapport à l'autre et s'intersectant. • - un premier canal (3) qui comprend une entrée et une sortie, un deuxième canal (4) qui comprend au moins une sortie. • - deux milieux peuvent être conduits au choix à l'entrée du premier canal, ensemble ou séparément. Le premier milieux est sous haute pression, l'autre sous basse pression. • - les deux entrées du premier canal comprennent chacune un clapet anti-retour (12). • - les sorties du deuxième canal comprennent chacune une soupape de surpression (6). • - une conduite de dérivation (7) est raccordée à chaque sortie du deuxième canal. • - les soupapes (6) du deuxième canal sont ouvertes par la pression du fluide de nettoyage haute pression lorsque celui-ci entre dans le canal (4). • - la tête de buse (2) est montée de manière à pouvoir tourner autour de l'axe du premier canal et entraînée avec un sens de rotation commutable.
