Abstract

1431118 Trickle flow irrigator G GILEAD 6 Dec 1973 [17 Jan 1973] 56501/73 Heading A1B A drip or trickle irrigator comprises contiguous, concentric pipes at least one of which has a helical groove that defines a liquid flow path between them. The inner pipe discharges water into the path via apertures which are axially spaced from discharge openings in the outer pipe. In Fig. 1 the inner grooved pipe 1 has apertures 2 axially spaced from the outer pipes openings 4. The outer pipe may alternatively be grooved and the inner pipe smooth. Alternatively both pipes can be grooved. The outer pipe may be in sections, the spaces between which define the discharge openings. The flow rate may be controlled by varying the axial spacing or by selectively using stoppers in the outer pipes openings. A grooved or smooth sheath may enclose the pipes. [GB1431118A]

Claims (8)

WHAT IS CLAIMED IS:
1. An irrigation device comprising: an elongated continuous hp1low hose for conveying fluid through the interior thereo and formed with a helical fluid flow passage of predetermined pitch between the inner and outer surfaces thereof* said helical passage having an axis substantially coaxial with the longitudinal axis of said hose; a plurality of holes extending through said inner surface of said hose at predetermined spaced axial distances along said hose, each of said holes coupling the interior of said hose to said helical passage for fluid transmission therebetween; a plurality of fluid discharge ports extending through said outer surface of said hose each being disposed a predetermined axial distance along said hose from a respective one of said holes in said inner surface and each coupling said helical passage to the region exterior of said hose; whereby fluid flowing axially through the interior of said hose flows outwardly from said interior of said hose through each of said plurality of holes into said helical passage and thence through said helical passage for discharge through each of said plurality of ports, the fluid discharged from each of said ports being selectively determined by the axial length of said helical passage between respective adjacent ones of said holes and ports*
2. · An irrigation device according to Claim 1 wherein said elongated continuous hollow hose is formed of inner and outer coaxial tubes having confronting surfaces in tight contact, at least one of said tubes being formed with a helical groove in the respective confronting surface, thereby defining with said other confronting surface said helical fluid flow passage; the inner surface of said inner coaxial tube defining said inner surface of said hose, and said outer surface of said outer coaxial tube defining said outer surface of said hose.
3. An irrigation device according to Claim 2 wherein tube has an ungrooved inner surface and wherein said inner tube is formed with said helical groove* thereby defining a helical ridge of a diameter substantially equal to the inner diameter of said outer tube*
4. An irrigation device according to Claim 2 wherein said inner tube has an ungrooved outer surface and wherein said outer tube is formed with said helical groove, thereby defining a helical ridge of an inner diameter substantially equal to the outside diameter of said inner tube*
5. An irrigation device according to Claim 2 wherein said inner and outer tubes are each formed with a helical groove and each defining a helical ridge and a helical valley; said tubes being disposed such that the helical ridge of said outer tube is in tight contact with the helical ridge of said inner tube to define said helical fluid flow passage*
6. * An irrigation device according to Claim 1 and further including a plurality of removable stoppers selectively disposed within respective ones of said ports in said outer surface to prevent f uid discharge therefrom*
7. An irrigation device according to Claim 2 wherein said outer tube is formed of a plurality of unconnected axially spaced sections* to define one or more sections at which the outer surface of said inner tube is exposed to the region exterior to said hose for discharge of fluid therefrom.
8. An irrigation device according to Claim 7 wherein said unconnected axially spaced sections are each slidable axially along the outer surface of said inner tube to control the flow rate of the fluid discharge* COHEN ZEDEK & SPISBACH P.O. BOX 33116, TEL AVIV. ATTORNEYS FOR APPLICANT
