Abstract
A cleaning systemhaving nozzle assemblyfor a pressured fluid stream entrained with abrasive that includes a pressured fluid receiving portionadapted to accommodate a pressured fluid dispenser. An abrasive entrainment chamberis oriented to accept pressured fluid jetted thereacross from the pressured fluid dispenser. The abrasive entrainment chamber is adapted to establish a venturi suction responsive to pressured fluid being jetted thereacross. An access portis provided in fluid communication with the abrasive entrainment chamber for permitting suction of abrasive into the abrasive entrainment chamber for entrainment in a pressured fluid being jetted thereacross. A spray enclosureis positioned at the abrasive entrainment chamber and oriented to receive pressured fluid dispensed from the pressured fluid dispenser at the pressured fluid receiving portion. The spray enclosure is configured to substantially conform to a spray patternof pressured fluid jetted from the pressured fluid dispenser with minimized influence on the spray pattern at side-edge portionsthereof for promoting substantially uniform dispersion of pressured fluid and abrasive across the spray pattern.
