ABSTRACT:
In a self-propelled swivel for directing high pressure streams of water in a rotary path against a surface to be cleaned, a plurality of permanent magnets are mounted on a rotary cage and rotate in close proximity to a sleeve of electrically conductive material, generating eddy currents in such sleeve and hence heating the sleeve. Low pressure water leaking through a seal provided in the path of the high pressure water is diverted to cool the portion of a casing surrounding the heated electrically conductive sleeve to provide braking of the rotational speed of the rotating nozzle heads without creating excessive localized heating within the housing.
