Abstract
The invention concerns a spray nozzle comprising a central swirl chamber ( ) in which the fluid to be sprayed penetrates by tangential channels ( ) producing a swirl axis perpendicular to the longitudinal axis (I—I). The fluid comes out of the swirl chamber ( ) through a coaxial outlet passage ( ). The nozzle comprises a rear coaxial recess ( ) dimensioned and shaped so as to inhibit any residual outflow of fluid through the coaxial outlet passage ( ) when the fluid supply is interrupted at the spray nozzle inlet ( ).
