<p>A drop-by-drop irrigation hose or pipe (1) made of a synthetic material with thermosealed inner emitter elements (2) having filter means (4) and labyrinth paths (6) leading to outlet chambers (5) is proposed, wherein said emitter elements (2) comprise interconnecting means for interconnecting said filters (4) and labyrinth paths (6) to said outlet chambers (5) in turn connected to the outside through perforations (9), said interconnecting means allowing to improve the water delivery safety even in case of a localized clogging of the labyrinth paths (6), owing to a simultaneous bilateral operation of said outlet chambers.</p> |
