ABSTRACT OF THE DISCLOSURE A powder sprayer for the powder coating of an object is pro- vided with an annular charging channel (9) for electrostatic charg- ing of the powder. The channel is defined by an inner, longitudinal rod (8) and an outer tube (7), both being manufactured of elec- trically insulating material. The rod (8) is centred in the tube (7) by means of spacer and turbulence members (10) with vanes which are obliquely inclined or helically configurated in relation to the lon- gitudinal direction of the sprayer. In order to improve the charging and blending of the powder, the turbulators (10) are arranged pair- wise after one another, each with a plurality of vanes which are distributed about the rod (8) so that through flow channels are formed between the vanes. The vanes in adjacent turbulators (10) are, in this instance, offset in the cirumferential direction in re- lation to one another, so that the leading edges of the vanes in a downstream turbulator (10) lie in register with the through flow channels in an upstream turbulator (10).
