ABSTRACT:
A nozzle device includes an axially extending tubular, cylindrical outside part; and a cap threaded on the outside part at the front or discharge end of the device and having a discharge bore composed of a rearward cylindrical portion having a first diameter; a frontal cylindrical portion having a second diameter less than the first diameter; and a frustoconical portion connecting the rearward and frontal cylindrical portions with one another. An axially extending inside part is coaxially received in the outside part and has an outer wall defining, with the inner wall of the outside part, an annular space for guiding gas therethrough. The annular space is axially adjoined by the discharge bore of the cap. The inside part further has a forwardly conically tapering end portion projecting into the frontal cylindrical portion of the discharge bore of the cap; an axial bore for guiding a viscous material therethrough; and a nozzle bore axially adjoining the axial bore and having an outlet opening for discharging the viscous material. The nozzle bore outlet opening is situated within the frontal cylindrical portion of the discharge bore of the cap. A port is provided in the outside part for introducing the gas into the annular space. At least three support lugs are positioned in the annular space in engagement with the inner wall of the outside part and the outer wall of the inside part for coaxially positioning the inside part relative to the outside part.
