ABSTRACT:
A drip irrigation system which includes a flow control valve having an inlet opening which constricts in response to pressure increases to provide a uniform flow despite pressure variations. The inlet opening of the valve has a rectangularly cross-sectioned central section and end sections which are non-rectangular, such as triangular or semi-circular, in cross section. During normal flow conditions the rectangular central section of the inlet opening is pressed closed and irrigation liquid flows at a constant rate through the two end sections.
