Abstract (en)
[origin: EP0429736A1] The nozzle comprises an inlet tubular element (4) for the main liquid, followed by a first chamber (A) having internal (2) and external (5) walls which are conical and diverging. The external wall (5) continues the inlet tubular element (4). The internal wall (2) has its apex facing the axis of the inlet tubular element (4). The external wall (5) is pierced by holes (6) through which at least one additional fluid is sprayed into the said first chamber (A), which chamber communicates, via other practically longitudinal holes (10) pierced in the periphery of the base (9) of the said internal wall (2), with a second chamber (B) bounded by a converging conical lateral wall (13) which emerges into a relatively long outlet tubular element (14). The peripheral space between the internal (2) and external (5) conical walls of the first chamber (A) is closed by a cylindrical ferrule (15). <IMAGE>
