ABSTRACT:
A sewer cleaning nozzle is provided for attachment to a hose for supplying cleaning fluid through the hose to a number of nozzle tips carried on the nozzle body for providing a sweeping action for material collected in the sewer pipe as the nozzle is pulled forwardly by pulling on the supply hose. The nozzle body includes a central pipe portion and a rearwardly mounted chamber portion attached to the pipe portion. The chamber portion defines a radial front face carrying a plurality of nozzle tips at angularly spaced positions. A conical deflector within the chamber deflects cleaning water along the pipe portion outwardly of the chamber to a curved wall portion of the chamber causing the water to move smoothly around the chamber forwardly to the nozzle tips. Further nozzle tips are provided on the pipe portion having a reduced outward angle relative to the nozzle tips on the front face. A plurality of fins are attached to the pipe portion and the chamber lying in axial planes of the pipe portion with each fin being located between two of the nozzle tips. The fins are solid and imperforate and have inner edges immediately adjacent the chamber portion and the pipe portion.
