<p>A nozzle comprising a nozzle body (200, 400; 6,8) equipped with a plurality of groups of orifices (220, 225) arranged around its periphery. A bladed wheel (300; 7) is arranged in a chamber in the nozzle housing, where the bladed wheel divides the internal chamber into an inlet (120) and an inner chamber (210). The bladed wheel is arranged so as to be able to rotate together with the nozzle body in order thereby to obtain a further increase in pressure than that known from other nozzles.</p> |
