Abstract
An emitter unit to be integrally bonded to an internal surface of a conduit and comprising an elongated housing, a housing inlet adapted to communicate with an interior of said conduit and a housing outlet adapted to communicate with a conduit outlet. An elongated, flow-restricting flowpath is formed in the housing having a flowpath inlet communicating with the housing inlet and a flowpath outlet communicating with the housing outlet. A resiliently flexible membrane is mounted in the housing which is of closed box-like shape and is constituted by an elongated receiving member and a correspondingly elongated cover member. Projections and recesses are formed along the lengths of elongated rim portions of the members and are directed substantially transversely to longitudinal axes of said members such that projections of one member are adapted to form a close pressure fit within corresponding recesses of the other member.
