Spray gun

Abstract

The spray gun or airbrush gun was first patented in 1893 by Charles Burdick. The newly constructed and built spray gun is built similar to that first model. The spray gun (Illustration 5, Illustration 6) consists of three units—air valve, trigger mechanism and fluid body—which have been fitted inside the gun body (12 mm diameter and 13 cm length). The axial motion of the trigger mechanism is 8 mm. The trigger mechanism can be pulled back with a ball-shaped lever and the air valve opens. The compressed air then streams through the air inlet tube into the air outlet tube. The air outlet tube has been put into the fluid reservoir, and the over-pressure created in this reservoir pushes the fluid to the ground and makes it go through the tube and into the tip.
