ABSTRACT:
A conduit-cleaning nozzle mounted via a swivel on the front end of a high-pressure hose has a nozzle body which is elongated along and generally centered on a longitudinal axis. This body has axially tapered front and rear ends and is formed at the rear end with an axial-symmetrical liquid-distribution compartment having at least one backwardly and normally downwardly opening liquid-ejection aperture. Water supplied at high pressure to this compartment is ejected downwardly and backwardly from the aperture. The angular orientation of the aperture is established by an off-center mass which is fixed in the nozzle body and which imparts to it a center of gravity which is offset below its central symmetry axis, so that the nozzle is self-righting.
