Abstract

Dispositif d'irrigation par stillation Il comprend un conduit 2 qui présente un orifice 4 de décharge d'un liquide d'irrigation, et une gaine élastique et extensible 6, entourant le conduit et recouvrant l'orifice 4. Les deux bords extrêmes 7 de cette gaine peuvent se dilater à une amplitude qui varie avec la pression du liquide régnant dans le conduit 2, afin de régler le débit auquel le liquide s'écoule de l'orifice 4, entre la surface extérieure du conduit et la surface intérieure de la gaine. Domaine d'application : installations d'irrigation.
