CA 2308507
The inventive spray nozzle (5) comprises a mixing chamber (15) into which a liquid (7) forming a first and a second liquid flow (12, 13) flows through two inlet openings (9, 10) and which has an outlet opening (30) for a spray jet (40), said outlet opening (30) being located downstream. A mixing chamber wall (16, 17) acts as a guiding surface for the flows of liquid (12, 13) and in the area of the outlet opening (30) is shaped in such a way that the flows of liquid (12, 13) meet at said outlet opening at an angle (.alpha.), hereby forming the spray jet (40). This spraying process delivers drops with high levels of kinetic energy and produces a broad, even fanning of the drop paths with an angle of impact (.alpha.) of almost 90~. As a result, the inventive spray nozzle can be used to spray large surfaces particularly evenly from a great distance.
L'invention concerne une buse à jet éventail (5) comprenant une chambre de mélange (15) dans laquelle un liquide (7) afflue par deux orifices d'admission (9, 10), constituant un premier et un deuxième flux de liquide (12, 13) et qui possède un orifice d'évacuation (30) en aval destiné à un jet de pulvérisation (40). Une paroi (16, 17) de la chambre de mélange qui agit comme surface de guidage pour les flux de liquide (12, 13), est formée au niveau de l'orifice d'évacuation (30) de telle façon que les flux de liquide (12, 13) se rencontrent au niveau de cet orifice d'évacuation (30) en formant un angle (.alpha.) et en constituant ainsi le jet de pulvérisation (40). Ce procédé de pulvérisation fournit pour un angle d'incidence (.alpha.) d'environ 90· des gouttes de grande énergie cinétique et un large éventail uniforme des trajectoires de gouttes. Cela permet de pulvériser de manière particulièrement uniforme de grandes surfaces à une grande distance avec la buse de pulvérisation.
