ABSTRACT:
A non-clogging non-pressure compensated drip emitter that utilizes one or more filters or one or more inwardly offset filters that have an inlet that projects inwardly toward a centerline of the hollow cylindrical emitter body and a labyrinth having only turbulent transfer zones after water enters the labyrinth, wherein the labyrinth couples the filter(s) or inwardly offset filter(s) to the pool. Prevents clogging by eliminating dead transfer zones where sediment can accumulate where no turbulence exists. Also prevents clogging when the filter is positioned downward as the inwardly offset filter rises above any sediment when the emitter is positioned in the field in this downward orientation. Also prevents clogging flat filter configurations that have filters offset radially, i.e., redundant filters per emitter.
