Abstract:
1. A spray head operated by a fluid under pressure for spray cleaning a surface comprising: a distributor body of a cleaning chemical corrosion-resistant material having a top surface and a front surface substantially normal to said top surface, said front surface and top surface meeting at a deflecting edge, said distributor body having a trapezoidal configuration in horizontal cross-section, said distributor body having at least one discharge aperture in said top surface leading from at least one bore in said body through which a jet of a cleaning chemical fluid is delivered under pressure, said at least one bore being arranged within the body at a forwardly directed angle to direct a jet of cleaning chemical fluid away from said top surface and toward said deflecting edge; and a spray nozzle support body adjacent the distributor body having an inlet adapted to receive a supply of heated carrier fluid under pressure, said spray nozzle support body having a spray nozzle located at the rear of and above the top surface of said distributor body and said discharge aperture for producing a substantially horizontal, generally planar, fan-like pattern of heated carrier fluid and directing said spray pattern at a slight angle to said top surface toward and against said deflecting edge whereby the jet of chemical cleaning fluid is emitted into the spray of heated carrier fluid prior to striking said deflecting edge and whereby the cleaning chemical fluid and heated carrier fluid are intimately mixed and the mixture is deflected from said edge as a mixed spray in a concentrated form that is directed toward a surface to be cleaned.
