(FR) DISTRIBUTEUR COMPRENANT UN ORIFICE DE SORTIE ET DE RETOUR AVEC RECOUVREMENT
Abstract
(EN)
A liquid dispenser is provided that includes a liquid supply channel, a liquid dispensing channel, and a liquid return channel. The liquid dispensing channel includes a first wall. The first wall includes a surface. A portion of the first wall defines an outlet opening. The liquid dispensing channel includes a second wall opposite the first wall. The second wall of the liquid dispensing channel extends along a portion of the liquid supply channel and along a portion of the liquid return channel. A liquid supply passage extends through the second wall and is in fluid communication with the liquid supply channel. A liquid return passage is positioned through the second wall and is in fluid communication with the liquid return channel. The liquid return passage overlaps the outlet opening of the liquid dispensing channel as viewed from a direction perpendicular to the surface of the first wall of the liquid dispensing channel. A liquid supply provides liquid that flows from the liquid supply passage through the liquid supply channel, through the liquid dispensing channel, and through the liquid return channel to the liquid return passage. A diverter member selectively diverts a portion of the flowing liquid through the outlet opening of the liquid dispensing channel.
(FR)
L'invention concerne un distributeur de liquide comprenant un conduit d'alimentation en liquide, un conduit de distribution de liquide et un conduit de retour de liquide. Le conduit de distribution de liquide comprend une première paroi. La première paroi comprend une surface. Une partie de la première paroi définit une ouverture de sortie. Le conduit de distribution de liquide comprend une deuxième paroi à l'opposé de la première paroi. La deuxième paroi du conduit de distribution de liquide s'étend le long d'une partie du conduit d'alimentation en liquide et le long d'une partie du conduit de retour de liquide. Un passage d'alimentation en liquide s'étend à travers la deuxième paroi et est en communication fluidique avec le conduit d'alimentation en liquide. Un passage de retour de liquide est positionné de façon à traverser la deuxième paroi et est en communication fluidique avec le conduit de retour de liquide. Le passage de retour de liquide recouvre en partie l'ouverture de sortie du conduit de distribution de liquide lorsqu'elle est vue depuis une direction perpendiculaire à la surface de la première paroi du conduit de distribution de liquide. Une alimentation en liquide amène un liquide qui s'écoule à partir du passage d'alimentation en liquide à travers le conduit d'alimentation en liquide, le conduit de distribution de liquide et le conduit de retour de liquide, jusqu'au passage de retour de liquide. Un organe déflecteur dévie sélectivement une partie du liquide en circulation à travers l'ouverture de sortie du conduit de distribution de liquide.
