ABSTRACT:
An in-line emitter unit comprising a tubular connector member having end portions adapted to connect together two successive lengths of irrigation conduit, a well structure formed integrally with an outer wall portion of the connector member, an inlet formed in said outer wall portion serving to effect communication between the interior of the tubular connector and the well structure, a cover member for the well structure, an elongated groove formed in an inner wall of the cover member, a recessed cavity formed in said inner wall and communicating with one end of the groove and being of extended dimensions as compared with the width of the groove, an outlet bore constituting a unit outlet and formed coaxially in a base portion of the cavity and having a rim area substantially less than that of the cavity, a resiliently flexible membrane located in the well structure and juxtaposed with respect to the inner wall so as to define with said groove a flow restricting flowpath, a second and opposite end of the groove communicating with the interior of the well structure; the arrangement being such that the membrane is displaceable towards and away from the base cavity portion of the cavity in accordance with pressure variations so as to stabilize the output rate of the emitter unit with respect to the variations.
