ABSTRACT:
A pressure compensated emitter for irrigation systems and the like includes a generally tubular hard plastic support body for mounting in a port or opening in an irrigation line with a flexible tubular flow control member mounted within the housing with a seal end sealingly engaging a seat in the outlet end of the housing with an inlet port extending toward the inlet opening in the housing with the flow control device being a flexible tubular member having an inlet section of a generally teardrop cross-sectional configuration of a first diameter and a tubular barrel of a second diameter of a generally cylindrical tubular cross section with the inlet section responsive to a first range of pressures and the barrel section responsive to a second range of pressures for regulating and maintaining a substantially uniform flow rate over a range of pressures.
