  • the sprayed liquid is supplied to a smaller step of the through hole 3 of the housing 1 and goes to the nozzle 4. Since its cross section is an oval, with a ratio of width to length from more than 1.8 to 4.0, the exhaust stream at the entrance to the nozzle 4 is compressed, and at the exit of it expands in a plane parallel to the oval, acquiring a flat fan shape with a width of 20-40 cm.

Cette buse de pulvérisation comprend un corps (1) avec une base se présentant sous forme de deux pétales (2) dépassant des dimensions du corps (1) et opposés l'un à l'autre dans un même plan, et comportant une ouverture traversante à degrés (3) à la sortie de laquelle se trouve un éjecteur (4) avec des parois coniques s'élargissant du côté du milieu à pulvériser. L'éjecteur (4) se présente sous forme d'un ovale avec une relation longueur-largeur allant de plus de 1,8 à 4,9, et possède une forme close. Les parois conniques de l'éjecteur (4) forme un angle d'ouverture de 20-80°. L'éjecteur (4) est délimité des deux côtés par des protubérances en plaques (5) disposées l'une en face de l'autre. Le corps (1) se présente sous forme d'un cône tronqué. La buse de pulvérisation comprend un moyen de fixation (6) se présentant sous forme d'une tige à une extrémité de laquelle sont disposés un embout et un suppport en forme de flèche, tandis que l'autre extrémité comprend un élément de fixation de deux buses. Le résultat technique consiste en une amélioration des qualités d'exploitation de la buse de pulvérisation.
