Abstract

Les longueurs (30) de voies en serpentin induisant des turbulences depuis les entrées (26) jusqu'au sorties (28) du passage (22) régulateur d'écoulement d'un tuyau d'irrigation goutte-à-goutte à émission continue sont agencées dos à dos par rapport aux sorties, de manière que les chevrons forment un angle à l'opposé de chacune des sorties, de manière à créer un écoulement turbulent parallèle à partir de deux entrées vers chaque sortie. Les entrées sont suffisamment grandes pour ne pas limiter le débit à travers les sorties. Cette disposition double le débit de chaque sortie sans changer les dimensions du passage régulateur de débit.
