Title (EN) ELASTIC DRIP TUBES FOR IRRIGATION
(FR) TUBES D'ARROSAGE ELASTIQUES POUR L'IRRIGATION
Abstract: front page image
(EN)A tube (12) for irrigation is made of elastic material and is pierced with a needle (22) to form a plurality of normally closed holes (24). A fluid is supplied by the tube at a low rate of flow. In response to the pressure of the fluid within such tube, the holes open (26), controllably releasing the fluid. An increase in the pressure of the fluid within the tube results in an increase in the hole size (28).
(FR)L'invention se rapporte à un tube (12) pour l'irrigation, qui est fabriqué en un matériau élastique et qui est percé au moyen d'une aiguille (22) destinée à former une pluralité de trous normalement fermés (24). Un liquide est acheminé par le tube à un faible débit. En réponse à la pression du liquide dans le tube, les trous s'ouvrent (26), laissant sortir le liquide de façon régulable. Une augmentation de la pression du fluide dans le tube entraîne un accroissement de la taille (28) des trous.
