Abstract: A fog generating system (20) includes a fluid feed conduit (22) and extension tube assemblies (26) spaced along the conduit (22). The assemblies (26) include nozzle fittings (40) coupled to extension tubes (32). Misting nozzles (44) are releasably engaged with the nozzle fittings (40), and are recessed within the nozzle fittings (40). Installation entails arranging the system (20) on an interior side of an installation form (90), and securing the nozzle fittings (40) using fitting plugs (50) so that an open ends (60) of the nozzle fittings (40) abut the form (90). The fitting plugs (50) further form a fluid resistant seal for maintaining the assemblies (26) under fluid pressure during installation. The system (20) is embedded in a concrete material (124) for the structure (120). Following removal of the installation form (90) and the fitting plugs (50), the misting nozzles (44) are installed within the nozzle fittings (40).

Abstract: A portable automatic misting device (20) uses a misting device assembly (38) to automatically disperses a mist (36). The misting assembly (38) includes a hollow cylinder (40) that forms a liquid reservoir (50) that is in fluid communication with a one-way valve (76,102) that permits liquid flow into the reservoir (50). The reservoir (50) has fluid communication with a misting nozzle (34) through a hollow plunger rod (28). A plunger (42), a spring (48) and a portion of the hollow plunger rod (28) are located inside the hollow cylinder (40). The spring (48) is biased to move the plunger (42) and the hollow plunger rod (28) to automatically shrink the liquid reservoir (50). In another embodiment, the plunger rod (28) is solid and the reservoir (50) has fluid communication with the misting nozzle (34) through a second one-way valve (106) that permits liquid flow out of the reservoir (50).

Abstract: A portable automatic misting device (20) uses a misting device assembly (38) to automatically disperse a mist (36). The misting assembly (38) includes a hollow cylinder (40) that forms a liquid reservoir (50) that is in fluid communication with a one-way valve (128) that permits liquid flow into the reservoir (50) from a liquid container (118). The reservoir (50) has fluid communication with a misting nozzle (34) through a hollow plunger rod (28). A plunger (42), a spring (48) and a portion of the plunger rod (28) are located inside the hollow cylinder (40). The spring (48) is biased to move the plunger (42) and the plunger rod (28) to automatically shrink the liquid reservoir (50). A second one-way valve (122) permits a passage of air into the liquid container (118) to equalize pressure therein.
