ABSTRACT:
A multiple nozzle swivel assembly for mounting on a cable support stretched across the interior of a chamber to be scrubbed with high velocity jet streams or stretched along an array of objects to be cleaned as the swivel assembly traverses the cable from one end to the other. The cable passes through a coaxial bore in an elongated shaft carrying both a relatively stationary an input member for supply of high pressure liquid to the assembly and a rotatable output nozzle-carrying spray head member. The shaft is monolithic with multiple angularly spaced bores around the central bore and parallel thereto and sealed from the central bore carry high pressure liquid from the input member to the output spray head member with very low drag bearings and liquid seals being provided between relatively rotating liquid carrying components. The assembly includes multi-directioned nozzle elements on a rotatable spray head. Positive drive to rotate the spray head is achieved with a rotational speed controlling motor. With the aid of low drag forces at bearings and rotating liquid seals, the spray head may be self rotated by reaction forces of jet streams from the head. The assembly may be pulled along the cable by an auxiliary device or it may be self-propelled along the cable by reaction of jet streams. For pulling the assembly along the cable a swivelled pulling bail is attached to the shaft.
