Abstract
A nozzle for spraying liquids includes a body pierced with a bore, preferably a cylindrical or cylindro-conical bore, and carrying an endpiece pierced with an orifice which may be frustoconical flowing out towards the outside or dihedral opening out towards the outside, this orifice being coaxial with a preferably hemispherical swirl chamber and opening out into the latter via a narrow passage. The endpiece is made from an elastically deformable material, and a restraining component, carried by the body and able to move with respect to the endpiece, acts on the endpiece in order to adjust the cross-section and/or the shape of the the orifice without substantially deforming the swirl chamber.
