Abstract: A dripper adapted to be bonded to interior of an irrigation pipe during manufacture and to be associated with an outlet opening in said pipe. The dripper comprises an outwardly facing surface adapted for the bonding, an outlet area associated with the surface, and at least one bulge near the outlet area. The bulge defines an outermost portion of the surface at least during manufacture of the pipe, and is adapted to form, when the dripper is bonded to the pipe, a raised outlet region in the pipe associated with the bulge. The bulge and outlet area are designed so as to form the raised outlet region suitable for at least a part of the outlet opening to be formed therein and be defined by the material of the pipe.

Abstract: A fluid flow regulator (20) comprising: a fluid inlet port (34) and a fluid outlet port (54); at least one open-faced flow control channel (60) defined by a planar bottom (62) and two sidewalls (64) that communicates with the outlet port (54) at a junction (66) and has a cross-section that decreases with distance from the junction; an elastic diaphragm (40); a support shelf (58) on which the diaphragm (40) seats and which supports the diaphragm (40) along a planar contour parallel to the bottom of each of the at least one channel (60); wherein to regulate fluid flow, with increasing inlet fluid pressure the diaphragm (40) covers portions of the open face that are farther from the junction (66) in a region where the cross-section decreases with distance from the junction (66).
