Abstract
In a powder spray device for the electrostatic coating of workpieces with powder at least partly comprising electrically conductive particles and having a powder channel (10) for delivering the powder to an outlet directed towards the workpiece the powder channel contains a local cross-sectional reduction. The cross-sectional reduction brings about a velocity increase of the powder in the powder channel, thereby preventing an adhesion of the powder to the inner wall of the powder channel.
