Abstract
The invention concerns a spray nozzle comprising a central swirl chamber (1) in which the fluid to be sprayed penetrates by tangential channels (7) producing a swirl axis perpendicular to the longitudinal axis (I—I). The fluid comes out of the swirl chamber (1) through a coaxial outlet passage (4). The nozzle comprises a rear coaxial recess (8) dimensioned and shaped so as to inhibit any residual outflow of fluid through the coaxial outlet passage (4) when the fluid supply is interrupted at the spray nozzle inlet (6).
