Abstract
A sprayer includes a spray gun and a hopper. An air source provides compressed air to the sprayer to both eject fluid from the spray gun as a spray and to pressurize the hopper. The spray gun includes passages for providing compressed air to the nozzle for spraying and to the hopper for pressurizing the hopper. The spray gun further includes a relief valve for venting pressurized air from the hopper. The hopper receives the compressed air through a port in the hopper, and the compressed air assists the flow of material out of the hopper and into the spray gun.
