ABSTRACT:
A spraying head for spraying material such as herbicides comprises a rotary distribution member (22) and a body made up of a housing (4) and a cap (6) which is rotatable on the housing (4). The housing (4) has a projection (28) which projects into an aperture (74) in the cap (6) to define an annular gap (78). The housing (4) and the cap (6) also define an annular cavity (72) into which material is introduced in use, the material then flowing to the member (22) through the gap (78). A device utilizing rotation of the cap (6) on the housing (4), is provided for adjusting the flowrate of material to the distribution member (22).
