Abstract A multiple chamber drip irrigation hose for distributing irrigation water and the like comprising, in combination, a primary and at least one secondary tube of flexible, water-impermeable material and joined at a common wall. Said common wall has a series of first holes placing the interior of said primary tube in communication with the interior of said secondary tube. Said secondary tube has a series of second holes leading from the interior of said secondary tube to the exterior. A flexible, filamentary line, ridge or groove is positioned within said secondary tube and forms a restricted path for water flowing from a first hole to a second hole. Optionally, at least one tertiary tube of flexible, water-impermeable material is joined to said secondary tube at a second common wall, with said second holes through said second common wall. Said tertiary tube has a series of third holes leading from the interior of said tertiary tube to the exterior and a flexible, filamentary line, ridge or groove is positioned within said tertiary tube.
A multichamber drip irrigation hose for distributing irrigation water and the like in controlled amounts, comprising: a primary and at least one secondary tube of flexible, water-impermeable material and joined at a common wall; said common wall having a series of first holes placing the interior of said primary tube in communication with the interior of said secondary tube; said secondary tube having a series of second holes leading from the interior of said secondary tube to the exterior; and with said secondary tube having a circular cross section divided into approximately equal upper and lower portions separated from each other by the walls of said primary tube, said lower portion of the secondary tube forming said common wall, said common wall having upper and lower surfaces, said common wall having at least one groove in each of said upper and lower surfaces to allow an increase in water pressure in the primary tube to flatten the adjacent secondary tube and close the groove in said lower surface limiting flattening of said secondary tube.

A multichamber drip irrigation hose for distributing irrigation water and the like in controlled amounts, comprising: a primary and at least one secondary tube of flexible, water-impermeable material and joined at a common wall; said common wall having a series of first holes placing the interior of said primary tube in communication with the interior of said secondary tube; said secondary tube having a series of second holes leading from the interior of said secondary tube to the exterior; and with said secondary tube having a circular cross section divided into approximately equal upper and lower portions separated from each other by the walls of said primary tube, said lower portion of the secondary tube forming said common wall, said common wall having upper and lower surfaces, said common wall having at least one groove in each of said upper and lower surfaces to allow an increase in water pressure in the primary tube to flatten the adjacent secondary tube and close the groove in said lower surface limiting flattening of said secondary tube.
Claim 3
Dependent Claim
54 words
An irrigation hose as defined in claim 1 including a flexible filamentary line positioned within said secondary tube and forming a restricted path for water flowing from a first hole to a second hole, said line being of smaller diameter than said secondary tube for movement of said line radially in said secondary tube.
