ABSTRACT:
A fluid-flow control device particularly useful as a dripper nozzle in trickle irrigation comprises a conduit member having an enlarged convex head attached to a cap defining a housing within which is enclosed a double-concave regulating member, the convex head having an axial passageway engageable by one face of the concave member, and the inner face of the cap having a depending boss engaging the other face of the concave member, the arrangement being such that during the flow of fluid through the passageway, the regulating member is set into rapid oscillating movement axially of the conduit member to rapidly open and close its outlet and thereby to control the flow of the fluid therethrough.
