ABSTRACT:
An elongated dripper unit comprising an enclosure sealed at either end thereof and formed with a liquid inlet and outlet, at least one longitudinal partition formed in said enclosure so as to divide the enclosure into at least two sub-enclosures and a plurality of lateral partitions each of which extends laterally across the other enclosure from the enclosure wall to an inner longitudinal partition so as to subdivide each sub-enclosure into a plurality of cells which communicate with each other via reduced-diameter communicating apertures formed in the longitudinal partition(s), said cells including an input cell communicating with said inlet, an output cell communicating with said outlet and a plurality of intermediate cells, a liquid flow path through said unit extending from said input cell to said output cell via said plurality of intermediate cells, the liquid pressure through said unit being progressively reduced as a result of passage through said communicating apertures and as a result of repeated abrupt directional changes, the available cross-sectional flow path through said apertures being substantially less than that through said cells.
