  • Publication number: 20230128483
    Abstract: In one example, a nozzle of a fluid material dispenser has a first nozzle body and a second nozzle body. The first body has a first inlet end, a first outlet end, a first outer surface extending, and a first inner surface. The first inner surface defines a first channel that can direct a fluid material from the first inlet end to the first outlet end. The second body has a second inlet end, a second outlet end, a second outer surface, and a second inner surface. The second inner surface defines a second channel that can receive at least a portion of the first nozzle body therein such that 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 can direct a gas to the second outlet end.
