Abstract

La présente invention concerne un circuit fluidique d'entretien (1) comprenant un réservoir (10), un circuit d'acheminement de liquide d'entretien (20) s'étendant du réservoir (10) jusqu'au moins un moyen de projection (60). Une source (40) de gaz sous pression est reliée à un circuit d'acheminement de gaz (41) qui débouche sur une enceinte (61) dudit au moins un moyen de projection (60). Le moyen de projection (60) comporte au moins un conduit interne (65) qui chemine dans ladite enceinte (61) et qui est relié au circuit d'acheminement de liquide d'entretien (20), ledit conduit interne (65) s'étendant jusqu'à une surface de passage de sortie de liquide (68) en contact avec le milieu extérieur.
