摘要
A fluid distribution device particularly useful as a drip irrigation emitter, comprises: a continuous plastic tube for conveying the fluid therethrough; and a plurality of individual plastic sleeves enclosing and fixed to the tube at longitudinally-spaced sections along the length of the tube; each of the sleeves being deformed to define a pressure- dropping fluid passageway between its inner surface and the outer surface of the section of the tube enclosed thereby; each of said tube sections having an inlet opening through the tube wall leading to the interior of the tube, and an outlet leading externally of the plastic sleeve.
