Abstract
An emitter unit comprises a pair of casing components and a coupling for coupling said components together via an interposed strip that extends beyond the components on all sides and is adapted to form a closed conduit such that one component is inside the conduit and one is outside. At least one of the components defines, together with the interposed strip, a flow restricting flowpath. Apertures are provided for effecting communication between said flowpath and the other component via said strip.
Claims8
An emitter unit comprising a pair of casing components, each having a surface, and oriented so that the surfaces face each other, coupling means for coupling said components together via a unitary strip that has continuous opposite surfaces, the strip being interposed between the components such that the surfaces thereof respectively engage the opposite surfaces of the strip which extends beyond the components to form a closed conduit within which fluid can flow, means on the surface of at least one component coacting with the surface of the strip engaged therewith for defining a flow restricting flowpath within which fluid flows in contact with both surfaces, and communicating means for effecting communication between said flowpath and the other component via said strip.
A drip level irrigation unit comprising:
- a. a conduit having a continuous outside surface and having a continuous inside surface of conducting liquid;
- a plurality of emitter drip units attached in spaced relationship to the conduit;
- c. each unit comprising a pair of casing components, each of which has a surface, the components being oriented so that the surfaces face each other, and coupling means for coupling the components together via the conduit which is interposed between the components so that the surface of one component engages the inside surface of the conduit and the surface of the other component engages the outside surface of the conduit;
- d. means on at least one of the components of a unit coacting with the surface of the strip engaged therewith for defining a flow restricting flowpath within which fluid flows in contact with the engaged surfaces;
- and
- e. communication means for effecting communication between the flowpath and the other component.
