Beschreibung
Zusammenfassung:	A coating dispensing device includes a trigger assembly for actuating the coating dispensing device to dispense coating material and a nozzle through which the coating material is dispensed. The coating dispensing device also includes a first port adapted to supply compressed gas to the coating dispensing device and a second port adapted to supply coating material to the coating dispensing device. The coating dispensing device further includes a generator having a shaft and a turbine wheel mounted on the shaft. Compressed gas coupled to the first port impinges upon the turbine wheel to spin the shaft, producing voltage. The dispensing device further includes an electrode adjacent the nozzle and coupled by circuitry to the generator to receive electricity therefrom to electrostatically charge the coating material. A circuit board assembly containing components of the circuitry is configured to partially surround and partially enclose the generator.
