| 摘要 |
The invention concerns an attachment (1) comprising a body wherein is formed an open conical chamber (5) including a nozzle (9) delimited by a sharp edge, behind which is provided a perforation (8) for supplying air under pressure and a nozzle (11) behind which is provided a perforation (10) for supplying liquid to be sprayed, said liquid being sucked into the chamber (5) by the effect of the depression brought about by the passage in (5) the air flow from the nozzle (9) to the outlet nozzle (6) and being finely fractionated and mixed with this flow by the effect of the turbulence prevailing in the chamber (5), which is aligned with the perforation (8) zone (8a), the longitudinal symmetry axis of the perforation zone (10), located upstream of the nozzle (11) is contained in the geometrical plane of the nozzle (9) perpendicularly intersecting the chamber symmetry axis.
