ABSTRACT:
A drip irrigation hose which is characterized by a tubular hose member having a major or primary channel or conduit and a secondary regulatory conduit or channel plate laminated between the lapped edge portions of the major channel with one edge of the secondary conduit plate communicating with the interior of the primary conduit and the liquid supply therein, and the opposite edge of the secondary conduit plate communicating with the surrounding. The secondary conduit plate can be shaped from an elongated strip of resilient film or sheeting and includes interior fluid flow paths in a sequenced, repetitive configuration which communicate with the high pressure liquid supply in the major or primary channel and with discharge openings provided in spaced relationship in the secondary conduit plate. The regulatory secondary conduit plate can be constructed by inscribing a desired pattern in an elongated strip of resilient film or sheeting and separating and/or orienting the inscribed conduit plate for insertion between the lapped edges of the primary channel film according to the teaching of the invention. In a preferred embodiment the paths through the secondary conduit plate are tortuous in configuration and serve to channel the water in turbulent flow and reduce the pressure of the liquid to a desired level at the discharge points. In another preferred embodiment of the invention the paths are shaped to define a vortex to reduce the pressure and to cause the water to drip or trickle from discharge apertures at a regulated flow rate.
