An improved air atomizing spray gun accommodates selective control over flows of air for atomizing liquid coating material into a conically-shaped spray and for forming the spray into a fan-shaped pattern. In one arrangement of the gun structure, respective supplies of atomizing and fan-shaping air are connected to the gun and separately coupled to atomizing and fan air outlet orifices. In another arrangement, only the supply of atomizing air is connected to the gun, and a valve on the gun adjustably diverts a portion of the atomizing air for fan-shaping purposes. |
