ABSTRACT:
An electrostatic spray device contains a tube-like spray element (3); at least one charging electrode (12) to transfer electrostatic charges to the powder; at least one counterelectrode (44) arranged in the vicinity of the charging electrode (12), which is connected to an electrical potential (20) different from the charging electrode (12), so that it takes up at least part of the free ions generated during electrical charging of the powder; at least one ring-shaped element (44; 68; 74) which forms or carries the counterelectrode (44; 64; 74, 76) and extends around the downstream segment (72) of the spray element (3), on which it is radially supported; at least one connection ridge (78) outside the spray element (3), which carries the ring-shaped element (74) at its downstream end (79) and can be attached to the spray element (3) by its upstream end; and an electrical connection between the electrical potential connection (20) and the counterelectrode (44) by way of the connection ridge (78).
