Abstract
A rotary nozzle device containing an outer casing (5) having an internal chamber (10) with a liquid exit (11) and a lateral surface of revolution upstream of the exit (11), and a rotary nozzle (20) positioned within the internal chamber (10) and traversed by an axial conduit (21) for liquid passage, and having its upper end, into which the axial conduit opens, positioned against and closing the exit (11), its final portion (24) being inclined to the nozzle axis. The nozzle (20) is positioned coaxially within the internal chamber (10) and has an outer lateral surface of revolution (20') which mates with at least one portion (12) of the lateral surface of the internal chamber, and furthermore has a lower portion (23) to which a turbine-bladed impeller is fixed, and further contains a diffuser (30) communicating with the liquid source to emit at least one jet directed to strike the turbine blades (25) so as to rotate the nozzle, and an internal channel which after the liquid has passed through the turbine blades (25) conveys it to the upstream end of the axial nozzle conduit (21).
