ABSTRACT:
A drip irrigation unit for insertion into a water supply pipe for reducing the flow through an outlet opening in the water supply pipe, includes a cylindrical member of a deformable elastomeric material fixed within the water supply pipe. The cylindrical member is formed with an inlet opening therethrough for conducting water from the interior of the water supply pipe to the outer face of the cylindrical member, and an outlet cavity in the outer face of the cylindrical member alignable with the outlet opening in the water supply pipe. A regulated flow-reducing pathway between the inlet opening and outlet cavity includes multiple, series-connected pressure-compensating chambers whose cross-sectional areas are changed by the deformation of the elastomeric cylindrical member to regulate the flow of the water in response to changes in the water supply pressure.
