A system (10), in certain embodiments, includes a spray device (12) including a first liquid passage (220) configured to flow a first liquid in a generally downstream direction toward a spray tip (205). The spray device also includes a second liquid passage (206) configured to flow a second liquid in a generally upstream direction such that the second liquid impinges upon the first liquid at an outlet to the second liquid passage. The upstream direction is substantially opposite from the downstream direction. L'invention porte sur un système (10), qui dans certains modes de réalisation, comprend un dispositif de pulvérisation (12) comportant un premier passage de liquide (220) conçu pour l'écoulement d'un premier liquide dans une direction globalement en aval vers une pointe de pulvérisation (205). Le dispositif de pulvérisation comprend également un second passage de liquide (206) conçu pour l'écoulement d'un second liquide dans une direction globalement en amont de telle sorte que le second liquide frappe le premier liquide au niveau d'une sortie du second passage de liquide. La direction en amont est sensiblement opposée à la direction en aval.
