ABSTRACT:
A drip irrigation hose formed with a plurality of outlets for discharging the water at longitudinally-spaced locations along the length of the hose includes a plurality of emitter elements secured to the hose at longitudinally-spaced locations along its length to define a plurality of turbulent flow passageways each in communication with the interior of the hose for discharging water from a hose outlet at a slow rate. Each of the turbulent flow passageways is defined by a relatively elastic first material co-extruded with a relatively inelastic second material both bonded to the hose with the relatively elastic material being pressure-deformable, as compared to the relatively inelastic material, to change the turbulent flow passageway of each emitter element in response to the pressure of the water in the hose at the respective emitter element.
