ABSTRACT:
A spray gun has a housing with a piston chamber formed therein. A piston is movable within the piston chamber. One or more control rods connect to the piston and move in conjunction with the piston. The piston has a gas passageway in it. The gas passageway has a mouth which fits against a piston sealing member to control the flow of gas through the passageway. Each of the control rods includes a gas channel through the control rod extending from one end of the control rod to the other end of the control rod. Each of the control rods is associated with a spray component cavity with one of the ends of the respective control rods fitting in to a spray component seat within the component cavity. Movement of the control rod with respect to the seat serves as a valve for the spray component within the particular component cavity. In response to movement of the piston away from the piston sealing member, the control rods move away from their respective seat for discharging of the spray components from the component cavities. Concurrently, gas flow through the gas passageway in the piston is fed to the control rods for simultaneous ejection of gas through the spray component seats with the spray component.
