DEFLECTION CONTROL OF LIQUID STREAM DURING DISPENSING

摘要

2075040 9112088 PCTABS00006 A method and apparatus for deflecting a liquid stream (26) during dispensing with a plurality of independently actuatable flows. A gun (20) has a nozzle (21) with an orifice (24) for dispensing a liquid stream (26). Blowout ports (33a-33f) surround the orifice (24) and are aimed at the flow path of the liquid stream (26), just beyond the end of the gun (20). The blowout ports (33a-33f) are connected via conduits (35a-35f) to a pressurized source (37).A timer (41) actuates solenoid valves (48, 38, 39) to control liquid dispensing through the orifice (24) and the flows from the blowout ports (33a-33f). By coordinating liquid dispensing with the directional flows, the liquid stream (26) may be deflected to achieve a desired dot or spray distribution pattern on a substrate (27) or uniform spray coating of the inside surface of a can.
