A fluid dispensing device having a housing assembly, a conduit assembly, and a shut-off valve assembly. The conduit assembly engages the housing assembly to form a first valve assembly that prevents fluid material from reaching a mixing location in a closed configuration and allows fluid material to reach the mixing location in an open configuration. The shut-off valve assembly comprises a valve housing and a valve member disposed within a valve chamber defined by the valve housing. When the conduit assembly is in the closed configuration, pressurized air within the valve chamber forces the valve member into a closed position against the valve housing to prevent pressurized air from reaching the mixing location. When the conduit assembly is in the open configuration, it displaces the valve member into an open position in which pressurized air can flow from the valve chamber, through the conduit assembly, and to the mixing location. When both fluid material and pressurized fluid are present at the mixing location, the pressurized fluid carries the fluid material against a surface to be coated.

[ I claim:] [1.] A fluid dispensing device for dispensing product comprising:a main housing assembly defining a main chamber and nozzle, product, and fluid openings that allow fluid communication between an exterior of the main housing assembly and the main chamber;a valve housing defining a valve chamber having a valve inlet and a valve outlet, the valve housing being arranged adjacent to the fluid opening and having an intermediate surface defining a portion of the valve chamber;a fluid passageway having an inlet portion and a nozzle portion, where the inlet portion is in fluid communication with the valve outlet and the nozzle portion is located adjacent to a mixing location that is adjacent to the nozzle opening, where the fluid flows along the fluid passageway from the valve outlet to the mixing location;a substantially spherical valve member disposed within the valve chamber, where pressurized fluid entering the valve inlet forces the valve member against the intermediate surface of the valve housing in a closed position to prevent pressurized fluid within the valve chamber from flowing out of the valve outlet and into the inlet portion; andactuator means operable between a closed configuration and an open configuration for allowing an operator to displace the valve member from the closed position into an open position to allow pressurized fluid in the valve chamber to flow out of the valve outlet, into the inlet portion, through the fluid passageway, out of the nozzle portion, and to the mixing location.
