A spraying head (SH) (1) has an axial drilled hole (ADH) (3), through which a substance to be sprayed is fed into the SH, where there is an adjusting device for regulating the yield rate. Crosswise to the ADH, the SH has a side drilled hole (SDH) linked to the ADH with an outlet at one end. From the SDH's other, a rotatable cylindrical element engages in the SDH and overlaps the ADH slightly. |
