Abstract
Spraying head having a head body forming a housing having an axis X defining an insertion opening and a substantially flat internal wall through which a central spraying opening extends and a spray nozzle, substantially tubular in shape and axially engaged in the housing of the head body via the insertion opening, the spray nozzle having an inlet that opens into a central internal duct and an external wall defining a central cavity centred on the central spraying opening and a plurality of swirl channels that open tangentially into the central cavity and communicate with the central internal duct. The swirl channels extend axially beneath the central cavity as far as the central internal duct, so as to be in direction communication therewith.
