ABSTRACT:
A rotating nozzle apparatus that is rotated by the reaction of highly pressurized water wherein, by rotating a nozzle attaching body 6 to vary the distance between a rectilinear propagation nozzle 7 and the rotation axis M of a support 5, the jet area of the rectilinear propagation nozzle which is rotated about the rotation axis of the support can be arbitrarily adjusted. A preferred embodiment comprises an apparatus wherein a rotation suppressing arrangement is positioned to be spaced a predetermined radial distance from the axis C of the nozzle attaching body, and the suppressing force of the rotation suppressing arrangement can be increased from the start where the suppressing force is substantially in the state of no applied load, proportionally to the increase of the rotational speed of the nozzle attaching body. In another embodiment a liquid outflow restrictor in the form of a labyrinth or a thread is interposed in the outlet opening adjacent the outer circumferential surface of a cover, and the fitted surface of the cover is substantially sealed with leaked liquid present on the restrictor surface, so that if splashed muddy water formed by rebounding highly-pressurized water from the ground at a high speed hits the fitted surface, the splashed water is prevented from entering the fitted surface.
