Abstract
An improved hand-portable pressurized sprayer apparatus of the present invention has a valve assembly that is sealably connected to a fluid supply tank and includes a safety valve constructed to respond to the occurrence of a predetermined maximum pressure value within the spray tank. The occurrence of pressure within the tank that exceeds the predetermined maximum value causes the safety valve to open, thereby allowing the release of excess tank pressure. The sprayer apparatus provides for the controlled pressurization of the supply tank using an external compressed air supply.
