  • Patent number: 7798428
    Abstract: A spray head with improved distributor body for a high pressure spray cleaning apparatus is provided. The spray head is carried on the end of a hand held wand with control valves to separately regulate flow through a pair of fluid circuits, the spray head having a nozzle that sprays heated water in a fan-like pattern against a deflecting edge of a distributor body. Cleaning chemicals are forced through an aperture into the fan-like pattern prior to its striking the deflecting edge to be intimately mixed with the heated water to produce a mixture that strikes the deflecting edge and is deflected therefrom in a highly concentrated form at a high velocity. An elbow guard provides improved protection for the chemical cleaning fluid flow line where it connects to the spray head. Also disclosed is a spray head that allows for the separate application of fluids delivered from separate supply sources.
