Abstract
A high-pressure rotary nozzle for cleaning the insides of pipes and vessels associated with the agricultural and petroleum industries, as well as in geothermal plants. The rotary nozzle provides a plurality of high-velocity, rotating, fluid streams to remove unwanted material from the interior surfaces of the pipes and vessels, wherein the nozzle comprises a central supporting shaft through which fluid flows into the rotatably mounted rotor body, the body being provided with jet-spray heads canted either forwardly or rearwardly of the line of longitudinal travel, and including thrust bearings located against each end of the body. The rotating speed of the rotor body is controlled by a plurality of free-floating bearing balls which bear against a stationary cup member as the body rotates on the central shaft. Guide members are secured to the cup member, allowing the nozzle to be continuously and centrally aligned during its longitudinal travel within a pipe.
