Abstract
A rotary nozzle cleaning apparatus is provided with an improved stem enabling an optimum flow of pressurized fluid while retaining structural strength. The stem is tubular in shape and formed with a series of triangular openings through the wall thereof. Alternating triangular openings are oriented with their apexes facing downstream of the fluid with interspersed openings oriented with their apexes facing upstream. The triangular openings are isosceles in configuration. The stem may be formed integral with an inlet cap of the cleaning apparatus or as a separate component.
