    摘要： A continuous flow tube containing a series of emitters arranged to discharge through a wall of the flow tube, each emitter forming a flush flow passage collapsible to form a drip flow passage at a preselected low flow tube pressure; the emitters having side walls of such area with respect to the area of the flow tube, that when exposed transversely to initial flow through the flow tube the emitters form externally a series of flow restricting valves which rapidly raise the flow line pressure to a value at which drip flow occurs, thereby minimizing the number of emitters undergoing flush flow.One embodiment of the emitter is adapted to be installed by forcing the emitter into the flow tube from the exterior thereof. Another embodiment utilizes a flow tube initially in the form of a web which receives the emitters and is then rolled into a tube with the margins of the web circumferentially overlapped and bonded. A further embodiment utilizes a circumferential extension of the web to form an insect guard for the emitter outlets.The emitters being capable of modification to permit orientation edgewise to flow to minimize restriction to flow, for placement in the region adjacent the intake end of the flow tube, thereby to increase the total number of emitters for a given supply of water to the flow tube.The embodiments also being capable of modification to provide a relatively rigid mounting base for the flexible emitter arranged to receive an insect guard cap or distributor tube of small dimension.

    摘要： An irrigation emitter including a fixed longitudinally extending passage wall element having a longitudinally extending restricted flow groove therein, and a flexible longitudinally extending passage wall element overlying the fixed wall element and contacting the fixed wall element along its side margins to define therewith a flush passage and adapted to collapse against the fixed wall element to confine flow to the restricted flow groove. One embodiment of the irrigation emitter having a single fixed wall element and flexible wall element forming a single flush passage and restricted flow groove. Another embodiment includes a ring of fixed wall elements and flexible wall elements forming a ring of flush passages and restricted flow grooves which may be modified for axial discharge or deflected discharge, and the grooves arranged for drip flow, or spray flow; and when arranged for spray flow, may be deflected to produce a segmental spray of selected circumferential extent.

    摘要： An irrigation emitter including a housing forming a chamber having diverging inlet and outlet walls, the diverging walls forming an apex which receives an end of an emitter plate therebetween; the emitter plate, when subject to pressure at the inlet wall below a predetermined low pressure occupying a position closing the inlet; the emitter plate, when subject to greater low pressure, forming momentarily with the outlet wall a flush flow outlet passage; the confronting surfaces of the outlet wall and emitter plate defining therebetween a drip flow passage. The emitter plate may be circular or rectangular and the portion of the chamber between the emitter plate and outlet wall may be enlarged to effect pressure reducing turbulent flow prior to discharge.
