Irrigation apparatus

DETAILED DESCRIPTION I claim: 1.
An irrigation apparatus for use with a cylindrical distribution pipe having apertures at spaced locations along the pipe, said apparatus comprising: a porous structurally rigid, solid body formed by sintering a quantity of plastic particles leaving interstitial spaces therebetween and thereby permitting flow of water therethrough, said body having a generally cylindrical shape with a central longitudinal axis adapted to be parallel with the axis of said distribution pipe, the lower portion of said body having a hollow portion extending therethrough with the longitudinal axis thereof parallel to the central axis of said body, said hollow portion having a cross-section which is at least semi-circular and wherein the greatest extent of said hollow portion into said body is at the central axis of said body, said hollow portion forming with said body two longitudinally extending, transversely depending sections which are adapted to conform to the exterior surface of said distribution pipe so that the apparatus can be engaged and retained in a self-supporting position by clipping the body in place about the distribution pipe over at least one of said apertures to distribute and diffuse a flow of fluid from said aperture into the area surrounding the apparatus at low pressure and low flow rates.




Description:
This invention relates to an apparatus for superficial or underground irrigation.
Briefly, the present invention comprises a porous filter element that can be connected to a hydraulic pipe at a suitable opening or aperture.
The hydraulic pipe may be a water pipe, pressurized or unpressurized.
The filter apparatus of the present invention is totally different from other irrigation systems utilizing porous pipes and affords advantages not found in prior systems.
The invention allows, in addition to irrigation and drainage, predetermined quantities of water to be delivered to selected points.
The apparatus of the present invention offers numerous advantages as contrasted to a perforated pipe embedded in the soil
