  • Patent number: 6568607
    Abstract: An emitter (30) has a body section (40) and an outlet chamber member (50). The outlet chamber member (50) has wings (52, 53) that have free ends. The free ends are deformable to form a number of varying sized diameters so that the emitter (30) may be used in various diameter conduits (100). The emitter (30) may also have a deeper well portion for use in attaching a fitting (90) thereto. The emitter (300) has a first chamber (332) and a second chamber (352) which also provide for a deeper portion for use in attachment of a fitting (90) thereon.

  • Patent number: 5413282
    Abstract: An emitter for use in irrigation comprising a housing and a flow restrictor in the housing. The housing has an inlet which can be connected to a source of irrigation liquid and an outlet. The flow restrictor reduces the pressure of the irrigation liquid to provide drip or trickle flow at the outlet. A spike flow inhibitor is provided in the housing for substantially preventing flush flow through the housing upon initiation of the flow of irrigation liquid through the housing. The flow restrictor is responsive to at least a predetermined reduction in pressure of the irrigation liquid at the inlet for causing flush flow through the flow restrictor.

  • Patent number: 4880167
    Abstract: Turbulent-flow emitter channel sections are vacuum-formed in an extruded flat plastic strip. The strip is then applied to a hose substrate, and inlet and outlet openings are formed at opposite ends of the channel sections. The strip may be hot-melt bonded to the substrate during a co-extrusion process, or it may be applied to the hose substrate in a separate operation. Flow rates are easily controlled without changing the structure of the strip by varying the number of channel sections in which outlet openings are formed.
