Abstract
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.
Claims4
A method of making a fluid distribution device, comprising:
- feeding a continuous plastic tube through a piercing station in which an opening is formed in the tube wall at each of a plurality of longitudinally-spaced sections along the length of the tube;
- subsequently applying a plurality of individual plastic sleeves with a plastic sleeve enclosing the tube at each of said longitudinally-spaced sections and the opening through the tube wall at each of said sections;
- and deforming each plastic sleeve to fix it to the tube section enclosed thereby and to define a pressure-dropping passageway between the inner surface of the sleeve and the outer surface of the respective tube section.
