Method and apparatus for high pressure article cleaner

Abstract

A cleaning system 210 having nozzle assembly 10 for a pressured fluid stream entrained with abrasive that includes a pressured fluid receiving portion 15 adapted to accommodate a pressured fluid dispenser 20. An abrasive entrainment chamber 25 is 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 port 30 is 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 enclosure 35 is 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 pattern 40 of pressured fluid jetted from the pressured fluid dispenser with minimized influence on the spray pattern at side-edge portions 45 thereof for promoting substantially uniform dispersion of pressured fluid and abrasive across the spray pattern.
