Abstract

An irrigation drip tape includes a flexible tube having an interior surface defining a primary flow path. A plurality of secondary flow paths are provided on the interior surface of the tube, the secondary flow paths in substantially axially aligned relationship along a length dimension of the tube. Each of the secondary flow paths are provided with an inlet region, a turbulence-inducing region, a pressure compensation region, and an outlet region having one or more outlets. The outlet region includes a chamber having side walls and upper and lower surfaces with one or more raised surfaces between the upper and lower surfaces to prevent the upper and lower surfaces from engaging and shutting off flow to the one or more outlets as a result of pressure in the primary flow path. The outlet region also includes at least one outlet slit in the tube in communication with the outlet chamber.
