Abstract
An airbrush of the double action type has an elongated unitary body having an axial passage for longitudinal movement of a needle supported therein. The rear end of the needle is carried by a guide slidably supported in the axial passage and normally urged by a spring in a direction such that the tapered front of the needle enters and closes the jet. A finger-operated lever formed of plastic and shaped to provide a 'living hinge' is supported in the body and arranged to engage the guide and move the needle against the action of the spring to control paint flow, and at the same time to open a valve to allow entry of compressed air or other substance under pressure. The maximum paint flow at the fully-operated position of the control lever is predetermined by adjusting the longitudinal position on the body of a closure cap which limits the movement of the guide. The airbrush has a minimum number of easily assembled parts and features a relatively simple paint-to-air seal disposed within the axial passageway.
