Abstract (en)
[origin: WO2014154373A1] The present invention relates to a spray-coating gun (1) for the spray coating of objects with coating powder. The front end region of the spray-coating gun (1) has a coating-powder spray head (5) and the opposite, rear end region of said spray-coating gun has a coating-powder connection (12) and at least one compressed-gas connection (13, 14). Coating powder can be supplied via the coating-powder connection (12) to a coating-powder channel (11, 26) extending to the coating-powder spray head (5), while compressed gas can be supplied via the at least one compressed-gas connection (13, 14) to at least one compressed-gas channel (9, 28; 10, 29) extending to the front end region of the spray-coating gun (1). In order to optimize the coating quality which can be achieved with the spray-coating gun (1), it is provided according to the invention that the compressed-gas channel (9, 28; 10, 29) has at least one compressed-gas branch (35, 36) via which at least some of the compressed gas added to the compressed-gas channel (9, 28; 10, 29) is supplied to the coating-powder channel (11, 26) in order to adjust a powder/air mixture necessary for atomizing at the coating-powder spray head (5) and/or for homogenizing the coating powder supplied to the coating-powder channel (11, 26).
