Abstract:
A spray gun having a central axis; a cap with a spray nozzle; a propellant inlet; a propellant valve for controlling delivery of a propellant along a plurality of propellant passages to the spray nozzle, the propellant valve having an open position and a closed position; a fluid valve for controlling delivery of fluid to the spray nozzle; and a common activation member provided on the a the spray gun adapted to control both the propellant valve and the fluid valve; whereinthe plurality of propellant passages from the propellant inlet to the cap are substantially linear; the propellant valve is operable linearly, substantially parallel to the central axis of the spray gun; the propellant inlet is located forward of the common activation member whereby the propellant valve in the open position provides an unimpeded aperture at the propellant inlet to the plurality of propellant passages; and an adjustment device is provided with the fluid valve to enable adjustment, separately from the propellant valve, of the amount of fluid flowing through the fluid valve, such that in one mode of operation the adjustment device is arranged to maintain the fluid valve closed when the common activation member is operated thereby enabling only propellant to be delivered to the spray nozzle.
