<p>A unibody pressure-compensating emitter (24) is provided for use in a drip irrigation hose. The emitter comprises a top wall (5) and two side walls, and optionally front and back walls. The emitter (24) can further comprise a bottom wall, or the bottom side of the emitter can be enclosed by the wall of the hose. The walls of the emitter define a flow section (28) therebetween. The flow section (28) comprises an inlet section (26), an outlet section, a pressure-compensating section (45), preferably between the inlet section (26) and outlet sections, and at least one resistance element (47), preferably between the inlet section (26) and the pressure compensating section (45). At least one of the emitter walls is capable of deforming into the pressure-compensating section (45) with increased water pressure in the hose.</p> |
