Abstract

The device has a spray head (1) for spraying the coating material and a valve (6) for opening and closing the outlet channel (7) of the spray head, whereby the outflow rate of the sprayed material can be adjusted and controled. The atomizer contains a dosing valve as control element for the outflow rate of the coating material whose drive (9) can be controled to adjust the outflow rate.
