ABSTRACT:
A spray nozzle which is non-plugging and selfcleaning. The nozzle has a central main conduit with an externally mounted water discharge assembly encircling it at its front opened end. A mixture of air and a sealant is forced through the main conduit until it is expelled from the conduit's inwardly tapered front opened discharge end. The water discharge assembly, in the preferred embodiment, has two spaced concentric rings joined together. The rearmost ring serves to mount the assembly to the main conduit and to support a second ring having an internal hollow water conduit section. Near the discharge front end, the front ring is attached to the rear ring by several supporting mounts. The front or outer ring has a plurality of water discharge jets or openings which encircle the front of the main conduit and are fed through their internal hollow section by a water conduit. A tapered surface of the outer ring which faces towards the main conduit cooperates with the gradually tapered outer surface of the main conduit to form an air passage therebetween which encircles the discharge end. As the air-sealant mixture is forced through the main conduit, an air flow is induced in the air passage by the air flow in the main conduit. This induced air flow is between the main conduit and the front ring. This induced air flow serves to remove externally mixed material from the nozzle before the same falls on the water jets.
