Abstract

A drip irrigation tube having a plurality of sequentially placed emitters formed on an interior wall of the tube. Each emitter employs a series of parallel flowpaths axially positioned along the tube to provide for closer proximity of inlet ports to discharge chambers thereby providing for closer spacing of the emitters. Overlapping of the inlet portion of the sequentially positioned emitters with the outlet portion of any preceding emitter provides for even more compact positioning of the emitters along the tube.
