An electrostatic powder spray gun comprises a powder cup and is constructed such that the powder cup comprises a removable cover which is secured to the pistol tube of the gun in an easily-detachable manner, whereby a conveying tube and an air tube extend through the cover and are held thereat. The air tube projects beyond the cover and, given the cover secured to the pistol tube, projects into a spring-loaded discharge valve of the compressed air feed line and thereby holds the same in the open position against spring pressure. Given the cover secured to the pistol tube, the orifice of a powder channel extending in the pistol tube is constructed as a connection for a powder feed line leading from a remote powder preparation system. |
