Abstract
An apparatus is supplied for a self adjusting regulator suited for an irrigation emitter. A curved flow channel is integrated into a concave dome shaped surface. A deformable member deforms to approach the surface to adjust the resistance to flow. The concave dome shaped surface may match a deformed shape of the membrane. Irregularities in the interface between the surface and the deformable member are configured to achieve a desired discharge under varying flow conditions. The deformable member may activate an inlet filter cleaner by pushing a ram and thereby unclogging the filter.
