| 摘要 |
The present invention relates to an arrangement in a spray mouthpiece (2) arranged on the outer free end of a spray tube (1). The said mouthpiece (2) is adapted by means of intersecting flow passages (7) to atomize liquid which is fed to the spray tube (1) under pressure. The arrangement according to the invention is characterised in that it comprises an elongated sleeve (3) which is adapted to be carefully placed on the said free end of the spray tube (1). The sleeve (3) is designed with an end face on which is a centrally located mouthpiece opening (5). In the sleeve (3) is a cylindrical body (4) essentially connecting with the end face. The said body has grooves (6), which with the sleeve form at least two ducts (6) communicating with the tube (1). From the tube end the ducts (6) run approximately axially up to the end face. By means of the said intersecting flow passages (7) formed on the end face of the body, the ducts (6) are connected to a chamber (8) connecting preferably co-axially with the mouthpiece opening (5).
