Abstract: A powder-spraying appliance for electrostatic powder coating of work pieces. In order to achieve particularly good charging of powder particles, the powder-spraying appliance contains a chamber, into which a powder/air mixture is introduced transversely to a spraying direction via a supply conduit. An earth electrode and a plurality of high-voltage electrodes are disposed in the chamber. All of the electrodes are flushed with cleaning air in order to avoid powder deposits on the electrodes.
