| 摘要 |
The invention relates to a spray gun apparatus (10) for spraying a fine film coating of liquid, such as paint, lacquer or bond, onto a surface. The spray gun comprises a main body (12) having a fluid throughbore (22), a gas throughbore (16), and a main trigger lever (80) for allowing a user to spray fluid from the gun. A fluid flow adjustment mechanism (52, 58, 74) facilitates adjustment of the quantity of fluid sprayed from the gun for a given displacement of the main trigger lever (80). An engagement surface (86) is provided on the trigger lever and adapted to engage with a corresponding engagement surface (90) of the fluid flow adjustment mechanism. Pivoting movement of the main trigger lever (80) results in translational movement of at least a portion of the fluid flow adjustment mechanism to thereby selectively spray fluid from the gun upon displacement of the main trigger lever. |
