Zusammenfassung:A flat type pressure regulated drip emitter with a non-drain valve capabilities that is installable inside a water supply conduit during the conduit manufacturing process and characterized by that the emitter's non-drain valve function is executed independently and separately from its pressure regulation function, through a portion of the emitter's elastomer component that is strained and biased against the emitter's water inlet opening and is moveable towards and away from an additional opening (additional to the emitter's water outlet opening), exposed to the pressure prevailing in the emitter's water exit pool and therefore, at any given time, this portion of the elastomer component is exposed to the maximum differential pressure that prevails in the system-on its one side to the water pressure prevailing in the water supply conduit and on its other (second) side-to the approximate atmospheric pressure.
