Abrégé
(EN)
The invention relates to a nozzle for a spray system comprising a body (1) defining channels (14, 16, 18) for circulation of a first flow and a second flow, said channels (14, 16, 18) being configured so that the first flow opens between at least two blades of the second flow at the outlet of said channels (14, 16, 18) and so that at least one of the second flow blades has a sonic and/or supersonic velocity at the outlet of said channels.
(FR)
Buse pour système de pulvérisation comprenant un corps (1) définissant des canaux (14, 16, 18) de circulation d'un premier flux et d'un second flux, lesdits canaux (14, 16, 18) étant configurés pour que le premier flux débouche entre au moins deux lames du second flux en sortie desdits canaux (14, 16, 18) et pour que l 'une au moins des lames de second flux présente une vitesse sonique et/ou supersonique en sortie desdits canaux.
