An embodiment of the present invention is an air brush including a housing, a head assembly, and a trigger assembly. The housing has a main body with an air valve, reservoir and a handle. The head assembly mounts to the main body with a nozzle, nozzle cap, and a needle cap. The trigger assembly fits within the housing and includes a needle engaging the head assembly, a needle chucking guide, a needle chucking nut, a lever assembly, a spring guide and a spring device. The lever assembly actuates the needle to release compressed air and contents of the reservoir. The spring device controls release of the contents relative to the air flow through the air valve and nozzle. The spring device includes a first spring, a second spring, and a ring member. The ring member is positioned between the springs, and the springs have different strengths. |
