Abstract
An irrigation drip emitter, and methods relating to same, are provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. The emitter having at least one movable member for compensating for fluctuations in supply line fluid pressure. In one form the movable member includes a tapered baffle section movable between a first position wherein fluid is allowed to flow over the tapered baffle section and a second position wherein fluid is prevented from flowing over at least a portion of the tapered baffle section and the tapered baffle section effectively lengthening the extent of a pressure reduction passage. In another form, first and second movable members are provided for compensating for such pressure fluctuations. In another form, a plurality of inputs are provided which are movable between first and second positions to compensate for such pressure fluctuations.
