ABSTRACT:
A cavitating jet nozzle is disclosed for producing cavitation in a pressurized fluid such as a water used to clean a surface. The cavitating jet nozzle includes a pin received at a central position which lowers the pressure of the pressurized fluid such that cavitation bubbles form in the fluid. The pin is free-floating relative to a securing member which retains the pin in the nozzle, and is thus self-centering. The inventive cavitating nozzle is easily maintained since the pin is self-centering and need not be repeatedly centered. The pin preferably has an end face upstream of an outlet portion of the nozzle.
