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.

Abstract: A rotary impingement cleaning apparatus is configured for use in sanitary environments with a minimum of components to enable easy inspection and cleaning. The components of the cleaning apparatus are formed to fit relatively loosely to one another and promote self flushing and self drainage of cleaning liquid. A stator is mounted within a housing for diverting the flow of the pressurized cleaning liquid from axial to angular to impinge and rotationally drive a rotator stem or a rotor. The rotator stem or rotor causes an elbow to rotate around the vertical axis and a number of nozzles mounted to a nozzle housing to rotate around the horizontal axis.
