ABSTRACT:
A spray gun or air brush is disclosed and comprises a spray jet having a delivery orifice fed from a liquid reservoir, an air jet located in the vicinity of the spray jet, and means 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 into the air stream. An air valve is arranged in the means for conducting pressure air so as to control the passage of air to the air jet, and manually adjustable cam means, adapted to co-operate with a control valve incorporated in the spray jet, are provided to control the size of the delivery orifice and to control variation of the size of the orifice in a predetermined manner.
