Abstract
A method and apparatus for deflecting a liquid or powder stream during dispensing with a plurality of independently actuatable flows. A gun has a nozzle with an orifice for dispensing a stream. Blowout ports surround the orifice and are aimed at the flow path of the stream, just beyond the end of the gun. The blowout ports are connected via conduits to a pressurized source. A timer actuates solenoid valves to control liquid or powder dispensing through the orifice and flows from the blowout ports. By coordinating liquid or powder dispensing with the directional flows, the stream may be deflected to achieve a desired dot or spray distribution pattern on a substrate or uniform spray coating of the inside surface of a can. Additionally, protective structure may be added to the end of the gun nozzle to eliminate the adverse effects typically caused by accumulation of some deflected liquid at the end of the gun nozzle.
