  • Spray gun with common control of fluid and air valve
    Patent number: 6425533
    Abstract: The spray gun has an air cap that generates a spray mixture of liquid and air. The air cap includes a fluid valve for controlling the delivery of liquid and a separate air valve in the body of the spray gun is provided for controlling delivery of air. A control mechanism assembly for both of the valves is located axially within a central bore extending substantially the length of the spray gun. The control mechanism is actuated by means of a cam and follower arrangement with the cam surface provided on the rear of a manually operable trigger. The fluid valve is fully adjustable separately from the air valve but the control mechanism assembly includes a common control member that is in engagement with the control mechanism and operates both the fluid and air valves.
