Fluid dispensing nozzle with gas channel and method of using and assembling the same

A nozzle of a fluid material dispenser, the nozzle comprising:

• a first nozzle body having a first inlet end, a first outlet end, a first outer surface extending between the first inlet end and the first outlet end, and a first inner surface opposite the first outer surface, the first inner surface defining a first channel that is configured to direct a fluid material from the first inlet end to the first outlet end;
• and
• a second nozzle body having a second inlet end, a second outlet end, a second outer surface extending between the second inlet end and the second outlet end, and a second inner surface opposite the second outer surface, the second inner surface defining a second channel that is configured to receive at least a portion of the first nozzle body therein such that at least a portion of the first outer surface is inwardly spaced from the second inner surface so as to define a space between the first outer surface and the second inner surface, the space configured to direct a gas to the second outlet end,
• wherein the first nozzle body comprises a first body portion that defines the first outer surface, and an enlarged body portion having a cross-sectional dimension that is greater than a cross-sectional dimension of the first body portion such that, when the first nozzle body is received in the second nozzle body, the enlarged body portion spaces the first body portion from the second inner surface,
• wherein the enlarged body portion defines at least one bore that extends therethrough along a distal direction such that a gas can pass through the at least one bore along the distal direction and into the space,
• wherein the first nozzle body and the second nozzle body are configured to be positionally fixed relative to one another as the nozzle discharges the fluid material and a pressurized gas, wherein the second nozzle body is formed by an undivided single piece of material, and wherein an entirety of the first inlet end of the first nozzle body is disposed within the second nozzle body such that the second inlet end of the second nozzle body extends beyond the first inlet end in a proximal direction that extends away from the first outlet end along a longitudinal axis of the nozzle.
