ABSTRACT:
A casing mounted miniaturized emitter, penetratingly lodged within an orifice in the wall of a conduit containing fluid to be dispensed, emits the fluid at a constant output flow rate irrespective of the fluid pressure within the conduit. A pair of spaced apart annular flanges disposed about the casing define an annular channel for retainingly engaging the orifice in the wall of the conduit. An insert having a pair of downwardly depending flexible skirts with striae disposed on facing surfaces of the skirts is supported by the casing. The pair of skirts, in combination with the extent pressure on opposing sides of the skirts, regulate the size of the passageway through the emitter to maintain a constant rate of output fluid flow irrespective of fluid pressure variations within the conduit.
