ABSTRACT:
The self-rotating nozzle has a hallow shaft adapted for connection to a source of pressurized fluid. A body has an axial bore upon a central axis secured over one end of the shaft and has a counterbore. The shank with an end portion extends from the body into which the counterbore extends with the counterbore terminating in a pair of radial ports. A head bears against the body and is journaled upon the shank. A fastener upon the end portion retains the head against axial movement relative to the body. A pair of spaced jet flow orifices are mounted upon outer portions of the head extending generally parallel to the central axis but on oppositely extending axes inclined at a small acute angle to axes parallel to the central axis to provide a balanced rotational reactive power torque to the head, there being a pair of fluid passages in the head communicating with the ports and with the orifices respectively, the orifices adapted to provide high velocity streams of pressurized fluid to a surface to be cleaned.
