Abstract: A nozzle for atomizing a fluid is particularly suited for misting systems and generates a mist without any moving parts. The nozzle may be completely plastic for corrosion resistance, and may have a body cast as a unitary plastic article. The body may have a substantially cylindrical neck and a head integral with the neck and having a cavity that receives an atomizing insert. An occluder integral with the head may extend into the cavity such that the insert fits over the occluder and leaves a gap between the insert and the occluder. A fluid conduit disposed through the center of the neck may deliver fluid to the cavity. The fluid conduit may narrow at it approaches the cavity to increase fluid pressure in the head. One or more apertures from the fluid conduit into the cavity may be narrower than the fluid conduit to again increase fluid pressure.
