Title
(EN) LOW DISCHARGE EMITTERS
(FR) GOUTTEURS A FAIBLE DEBIT
Abstract
(EN)
High performance low discharge emitter (1) of a meander-like form, created by the addition of a thin vane (7) between the edges (4) of two successive reflectors (2) of the meander like path. The vane (7) interferes parallel to the primary flow of the water, is not in contact with the meander-like path, and creates around it two channels, a narrow one and a wide one enabling water to pass. Due to the arrangement of the meander-like form and the vane (7), all the quantity of water passes only through the high performance narrow channel, whereas the wide channel remains stand-by and inactive. Thus, a high water pressure drop is achieved, so that water discharge of the emitter (1) is reduced, and for ensuring a parallel connected wide stand-by path automatically activated as a by-pass in the case of blockage of the narrow high performance operating channel.
(FR)
L'invention concerne un goutteur (1) à faible débit et haut rendement décrivant un méandre et équipé d'un mince diffuseur (7) placé entre les bords (4) de deux réflecteurs (2) se succédant sur le méandre. Le diffuseur (7) fait obstacle en parallèle au premier écoulement d'eau, n'entre pas en contact avec le méandre et crée autour de ce dernier deux canaux, l'un étroit et l'autre plus large permettant le passage de l'eau. De par l'agencement du méandre et du diffuseur (7), la quantité totale d'eau passe uniquement à travers le canal étroit haut rendement, alors que le large canal est inactif et en attente. Ainsi, on provoque une chute de pression d'eau accentuée de manière à réduire le débit d'eau du goutteur (1) et à activer automatiquement le large trajet inutilisé monté en parallèle et servant de dérivation en cas de blocage du trajet étroit haut rendement opérationnel.
