The invention relates to a spray nozzle device of a window washing installation, especially for a windscreen (2), pertaining to a vehicle, said device comprising two narrowly adjacent spray nozzles (4) which are provided especially in a common spray nozzle module and can be individually adjusted in relation to the spray direction thereof. The aim of the invention is to enable, with a rational structure of the window washing installation, that is with as few individual elements to be supported on a window (2) as possible, optimum cleaning of the window and minimum interference with visibility during the operation of the window washing installation. To this end, one such spray nozzle device has the following characteristics: the two spray nozzles (4) are embodied as spray mist spray nozzles for producing fans of spray mist (5, 6) respectively having an apex in the associated spray nozzle opening; both spray nozzles (4) can be supplied with washing liquid produced thereby (4) for simultaneous spraying; and fans of spray mist (5, 6) are predominantly sprayed horizontally adjacently, perpendicularly to the window (2) to be cleaned.

L'invention concerne un dispositif gicleur d'un système lave-glace d'un véhicule, destiné notamment à un pare-brise et comprenant deux gicleurs (4) très proches l'un de l'autre, placés notamment dans un module gicleur commun et réglables individuellement quant à leur direction de pulvérisation. L'invention vise à obtenir une structure rationnelle du système lave-glace, c'est-à-dire permettant, avec le moins possible d'éléments individuels installés sur une vitre (2), un nettoyage optimal de la vitre, tout en réduisant au minimum la gêne à la visibilité occasionnée pendant le fonctionnement du système lave-glace. A cet effet, le dispositif gicleur selon l'invention présente les caractéristiques suivantes : les deux gicleurs (4) sont des gicleurs pulvérisant un brouillard de gouttelettes et produisant des éventails de brouillard (5, 6) ayant respectivement un point de crête situé dans l'ouverture de gicleur correspondante ; les deux gicleurs (4) peuvent être sollicités par le liquide de lavage pour une pulvérisation simultanée ; les éventails de brouillard de gouttelettes (5, 6) produits par les gicleurs (4) se trouvent, au moins pour la part la plus importante, horizontalement l'un à côté de l'autre en cas de projection verticale sur la vitre à nettoyer (2).
