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