Abstract: A fluid-atomization manifold (50) for use in a misting system (20) configured to distribute a fluid (24) and to render that fluid (24) into a mist (26) is provided. The fluid-atomization manifold (50) has an input connector (54) coupled to a connector (44) of an interface fitting (36) coupled to fluid-distribution tubing (34) of the misting system (20). The fluid-atomization manifold (50) has a plurality of output connectors (56), wherein a connector (48) of each of a plurality of fluid-atomization nozzles (46) of the misting system (20) is configured to mate with the connector (44) of the interface fitting (36) and is coupled to one of the output connectors (56) of the fluid-atomization manifold (50).

Abstract: A misting head system (24) configured to render a fluid (32) into a mist (36) is provided. The system (24) includes a misting head body (26) and a poppet (20). The misting head body (26) has a cylindrical chamber (28), an inlet (30) configured to pass the fluid (32) into the chamber (28), and an orifice (34) configured to pass the fluid (32) out of the chamber (28) and to render the fluid (32) into the mist (36). The poppet (20) has a cylindrical core (38) configured to force the fluid (32) to pass through a space (44) between the core (38) and an inner wall (46) of the chamber (28), a fracture band (54) coupled to the core (38), configured to center the core (38) within the chamber (28), and having a plurality of flutes (60) configured to fracture the fluid (32) as the fluid (32) passes through the space (44), and an orifice end (40) of the core possessing a plurality of symmetrically spaced slits (48) configured to further fracture the fluid (32).

Abstract: An atomizing nozzle (40) includes a body (44) having an fluid inlet end (50), a fluid outlet end (52), and a channel (54) located between the inlet end (50) and the outlet end (52). A free floating plunger (46) resides in the channel (54). The plunger (46) has a frusto-conical portion (64) facing the inlet end (50) and a cylindrical portion (62) facing the outlet end (52). The frusto-conical portion (64) causes the plunger (46) to resist getting wedged in the channel (54) so that a mist (102) having fluid particles of uniform size is ejected from the outlet end (50).

Abstract: A misting system (20) includes an atomizing nozzle (22) having a one-piece body (28). The one-piece body (28) has a passage (34) in which a plunger (36) resides and an atomizing orifice (30). The plunger (36) is inserted into the body from a fluid inlet end (38) of the body (28). A retainer (40) couples to the fluid inlet end (38) of the body (28) so that fluid flow into the passage (34) is not blocked but movement of the plunger (36) out of the passage is blocked. The retainer (40) may take a variety of forms, including a crimped portion of the body (28), a compressible elastic member (52, 72, 82), a cap (86) or plug (102).
