<p>A spray gun nozzle head (4) for atomizing a liquid using a flowing pressurized gas. The nozzle head (4) includes a central nozzle (30) having an orifice (31) for supplying the liquid to be atomized. A cap (32) having a funnel shaped chamber (42) is mountable over the nozzle to define an annular passage (43) for supplying the pressurized gas. The cap (32) has an orifice (45) alignable with the nozzle orifice (31) such that the nozzle orifice is recessed upstream from the cap orifice to define a region adjacent the nozzle orifice in which the liquid is atomized by the pressurized gas into a liquid spray prior to being expelled through the cap orifice.</p> |
