ABSTRACT:
A cleaning system210having nozzle assembly10for a pressured fluid stream entrained with abrasive that includes a pressured fluid receiving portion15adapted to accommodate a pressured fluid dispenser20. An abrasive entrainment chamber25is 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 port30is 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 enclosure35is 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 pattern40of pressured fluid jetted from the pressured fluid dispenser with minimized influence on the spray pattern at side-edge portions45thereof for promoting substantially uniform dispersion of pressured fluid and abrasive across the spray pattern.
