ABSTRACT:
A fluid assist airless spray nozzle for spraying a plural component spray system has a nozzle plate having an airless discharge orifice located therein for spraying a first component of the plural component system as, for instance, a resin component. A first fluid discharge orifice is located on one side of the airless discharge orifice and a second fluid discharge orifice is located on the other. Outboard of the first fluid discharge orifice is a first gas discharge orifice and outboard of the second fluid discharge orifice is a second gas discharge orifice. The first component of the plural component system as, for instance, a resin is supplied to the airless discharge orifice and a second component of the system as, for instance, a catalyst is supplied to the first and second fluid discharge orifices. A gas is supplied to the first and second gas discharge orifices. The resin is discharged from the airless discharge orifice in a resin fan. Fluid from the first and second fluid discharge orifices are directed toward this fan such that the fluid impinges upon the fan and becomes incorporated therein and helps maintain the shape of the fan. Gas discharged from the first and second gas discharge orifices impinge upon the fan downstream from where the fluid impinges thereon and further shapes the fan.
