Abstract: A self-cleaning pressure compensating drip emitter for controlling fluid flow through a hole in an irrigation line includes an enclosing sidewall having two ends, and formed with a ledge between the ends. A cover extends from the sidewall to establish an antechamber between the ledge and the cover. An entrance allows fluid from the irrigation line to enter the antechamber with little pressure reduction. An outlet extends into a fluid chamber established between the ledge and the second end of the sidewall. An opening allows pressure reduced fluid from the irrigation line to enter the fluid chamber. A membrane is positioned on the ledge for movement between a flushing configuration at low line pressures and an operational configuration at higher line pressures. In the flushing configuration, the membrane allows fluid to flow from the antechamber to the fluid chamber and through the outlet for flushing the emitter.

Abstract: One piece, in-line, water pressure compensating with self-regulation emitter, consisting of one regulator cylinder permanently embodied inside a water conduit on which conduit holes have been opened, at the point where the emitter is embodied, so that the water drips out onto the soil. The emitter self-regulates to provide a constant emission of water. This self-regulation is accomplished by a flexible part of the emitter body, which deforms in response to pressure variations within the water conduit.
