Abstract

A spray nozzle ( 11 ) includes a body ( 12 ) defining an axial cavity and having, housed in the cavity, from upstream to downstream in the liquid direction of flow X-X', a calibrating nozzle tip ( 33 ), a piece called divergent ( 19 ) and a piece called convergent ( 16 ). More particularly, the calibrating nozzle tip ( 33 ) and the convergent ( 16 ) are respectively integral with a plug ( 21 ) and the nozzle body ( 12 ), the plug being hermetically threaded into the cavity of the nozzle body ( 12 ) and including at least one gripping zone ( 22 ), while the divergent ( 19 ) is an independent piece immobilized in the cavity of the nozzle body ( 12 ).
