The nozzle body (1) longitudinal axis (3) is extended by a tubular section (10), pierced by an axial main supply channel (11). Secondary (16) and tertiary (17) supply channels open into this, having radial directions successive and coaxial to the longitudinal axis. The channels open (18) into a circular relaxation chamber (19). Grooves (34, 41) communicate to the opposite end, the jet orifice (23), in the nozzle external cylindrical wall (24). The grooves are cut in an annular nozzle (27,28) component conical face, joining another nozzle compartment. The relaxation chamber is toroidal, its major diameter being much larger than the tertiary channel.
