ABSTRACT:
A spray gun or air brush comprising a spray head which carries a liquid spray nozzle or jet fed by a tube depending therefrom into a liquid reservoir, an air jet positioned adjacent the spray nozzle and mechanism for conducting pressure air from a source to the air jet to cause a stream of air past the spray jet whereby a negative pressure induced in the latter draws liquid from the reservoir and into the air stream wherein it is entrained as minute droplets. A manually operable air valve, having a valve seat and a valve closure member movable towards and away from the seat, is situated in the air flow path to admit air to or to prevent it from reaching the air jet and a manually adjustable mechanism is provided to limit opening movement of the valve closure member so as to control the size of the air flow region between the valve closure member and the seat.
