发明名称 Drip irrigation system employing adjacently arranged flow-restricting passages
摘要 An elongated fluid distributing hose for use in an irrigation system for plants, vegetables, and the like. The hose incorporates a particular arrangement of a main supply channel for gross water movement, and a water distributing network for fine water movement. The major water pressure reduction takes place in the water distributing network made up of a series of first, second, and third fluid-restricting passages and is eventually released to the exterior of the hose through a series of discharge fluid-passing openings or outlet stations. A novel method and machine are employed to manufacture the hose embodying the teachings of the subject invention.
