Abstract

L'invention concerne un clapet gicleur d'eau dans lequel un rapport de mélange liquide-gaz approprié est obtenu du fait que le liquide giclé ne peut adhérer à un élément de buse et à une surface de paroi d'un passage de gaz. Un angle formé par une ligne tangentielle, à proximité du bord de sortie (34) d'un espace (26) de la buse, vers une paroi de séparation (28) et l'axe (A-A) d'un corps (12) du clapet est rendu plus petit qu'un angle formé par une ligne tangentielle (5), au niveau de la position où le corps (12) du clapet est en contact avec un siège de clapet (18), vers une paroi externe du corps (12) du clapet et l'axe (A-A) de celui-ci (12), contraignant un liquide giclé à l'extérieur du bord de sortie (34) de l'espace (26) de la buse de se diriger plus à l'intérieur par rapport au sens de la ligne tangentielle (5) vers la paroi externe, empêchant le liquide de se diffuser afin d'adhérer à une surface de paroi d'un passage de gaz, empêchant ainsi l'apparition d'un problème de variation dans un rapport de mélange liquide-gaz
