Abstract:
1. An ultra-high pressure waterjet nozzle assembly to infuse fluid into a high velocity stream of liquid to amplify the impact of the liquid against a work-piece for removing organic and inorganic surface coatings such as paint or deposits comprising: a nozzle body constructed and arranged for communication with an ultra-high pressure liquid; and an orifice means disposed in said nozzle body so as to be in communication with said high pressure liquid for concentrating said high pressure fluid into a high velocity substantially laminar liquid stream; and an infuser means connected to said nozzle body for injecting fluid, said infuser means constructed and arranged to transform said substantially laminar liquid stream into a substantially turbulent bubble rich waterjet wherein said ultra-high pressure liquid has a pressure of at least about 25,000 pounds per square inch.
