Abstract: There is provided a liquid atomizing spray gun of the general type that produce single, finite bursts of gas/liquid mixture which overcomes disadvantages of prior designs in that it does not depend for pressurizing and propelling gas on the squeezing of a trigger while aiming the device throughout the spraying stroke and in which a gas compressing piston is not driven by or otherwise directly mechanically linked to a trigger. These and other objectives are achieved in part by providing a spray gun with a chamber containing a gas tight piston that is reciprocable within the chamber, but wherein the piston is not reciprocated by the trigger. Instead, the piston is independently drawn to a rearward position for drawing gas into the chamber through a one way gas intake valve by the creation of a partial vacuum within the chamber. The piston is then released and biased forward to compress the gas within the chamber.
