| QUOTE: The answer is Yes, when you push down on the trigger, you should ONLY get air coming out the nozzle. When you assemble the needle into the brush, the needle should close off the hole in the nozzle so NO air will escape when you have air presure in the line. I hope this helps, |

Hmmm ... sorta right. You are right in that when you push down the trigger nothing but air should come out but the needle has nothing whatsoever to do with airflow. Air flows AROUND the nozzle, NOT through it. The airflow around the nozzle pulls paint out, it does not go through the nozzle and blow paint out. When you push the trigger down you open the air valve. Air then comes through the valve, through the small hole in the airbrush body (unscrew the air valve and you can see it) down a cavity bored in the airbrush body underneath the bore for the needle, out a hole in the front of the airbrush body (unscrew the head and you can see that one), through the holes in the aircap head (there are 6 of them on the Omni series) and then around the end of the nozzle. When you pull the trigger back it moves the needle back allowing paint to flow through the nozzle.
