Abstract

La présente invention se rapporte à une technique pour disperser efficacement un liquide sous forme atomisée par la réduction de liquide indisponible. L'invention décrit spécifiquement une buse de pulvérisation de liquide (30) comprenant : un corps (40) ayant un orifice d'éjection (45) destiné à éjecter le liquide ; une surface de collision (53) avec laquelle un écoulement d'éjection provenant de l'orifice d'éjection (45) entre en collision ; et un élément de support (51) qui est disposé au niveau d'une pièce de la partie périphérique de l'orifice d'éjection (45) dans le corps (40) et supporte la surface de collision (53). La surface de collision (53) pour disperser l'écoulement d'éjection sous forme atomisée est oblique par rapport à la direction d'éjection de l'écoulement d'éjection et amène l'écoulement d'éjection qui est entré en collision avec la surface de collision (53) à se disperser vers une région de dispersion principale (RG1). L'élément de support (51) est disposé à l'extérieur de la région de dispersion principale (RG1) de l'écoulement d'éjection qui est entrée en collision avec la surface de collision (53).
