Abstract (en)
[origin: WO9719759A1] The serpentine, turbulence inducing path lengths (30) from the inlets (26) to the outlets (28) of the flow regulating passage (22) of a continuous emitter drip irrigation hose are arranged in back to back fashion relative to the outlets in the sense that the chevrons angle away from each of outlets, so there is parallel turbulent flow from two inlets to each outlet. The inlets are sufficiently large that they do not limit the flow rate through the outlets. This doubles the flow rate from each outlet without changing the dimensions of the flow regulating passage.
