Abstract
A paint spray gun has a spray cap that is disposed in front of a nozzle of a gun body, and that is formed with a central spray hole, a set of mist forming holes, a set of mist controlling holes, a pair of horn projections, and a pair of orifices. Each horn projection is formed with an air passageway, which terminates in first and second outlet openings that are oriented in different directions relative to the central spray hole. Pressurized air that flows through the nozzle exits the spray cap at the mist forming holes, the mist controlling holes, the orifices, and the first and second outlet openings in the horn projections. Paint material is drawn but of a paint canister and flows through a nozzle orifice in the nozzle and the central spray hole in the spray cap for atomization.
