Patent ID: 6935583

Claim:
A coating-powder spray gun comprising an integral plastic gun housing having a rear open end and a front end; a high-voltage generator; a tubular powder-feed duct and a high-voltage chamber both running in a longitudinal direction of said gun from the rear open end of said housing, said tubular powder-feed duct issuing into the front end of the gun housing, and said high-voltage chamber receiving said high-voltage generator which is inserted in the longitudinal direction through the rear open end of said housing; at least one high-voltage electrode to which a high voltage generated by said high-voltage generator is applied to electrostatically charge the coating powder; and at least one electric jumper and an electrically conducting electrode jumper; wherein the high-voltage chamber is sealed at the front end of the gun housing by said gun housing; said at least one electric jumper passes in pressure-hermetic manner through the front end of the gun housings; the jumper is electrically connected or connectable within the high-voltage chamber to a high-voltage terminal of the high-voltage generator and is connected or connectable outside the gun housing to said electrically conducting electrode jumper for applying the high voltage from the high-voltage terminal to the high-voltage electrode.
