[origin: JP2017190188A] PROBLEM TO BE SOLVED: To provide a spray nozzle, in particular for a system for dispensing a pressurized fluid provided with a pushbutton, and a dispensing system comprising such a nozzle.SOLUTION: A spray nozzle (12), in particular for a system for dispensing a pressurized product provided with a pushbutton, includes a dispensing orifice (23) and a vortex chamber (22) in communication with the dispensing orifice (23). The vortex chamber includes a conical part (31) defined by a conical side surface (25). The conical side surface converges from an upstream end (26) toward a downstream supply end (27) of the dispensing orifice (23). The nozzle further includes at least one supply channel (24) of the vortex chamber, each supply channel (24) being in communication with the upstream end (26) of the conical part (31), the conical side surface (25) having at least one stepped part (33) provided with multiple steps (36).SELECTED DRAWING: Figure 2
