The spray nozzle includes a nozzle body ( 310 ), a swirl element ( 314 ) and an orifice disc ( 312 ). The nozzle body defines a central bore which extends between a fluid receiving section and a fluid discharge section and delineates a central axis and delimits an interior locating surface for swirl element and the orifice disc. The orifice disc includes a protuberance ( 374 ) associated with the downstream surface thereof which protrudes into the spray opening of the nozzle body.
