ABSTRACT:
A dosage gun includes a housing having a longitudinal bore therein which terminates at one end in an emission nozzle and pressure tanks which hold components of the dosage material. A dosage device is held in the bore and is designed as a nozzle needle for the gun. The dosage device contains a hollow needle and a dosage needle which is arranged in the hollow needle so that co-axial streams of material, one flowing inside the other, are ejected at the emission nozzle. In relation to the hollow needle, the dosage needle is, on the one hand, movable in order to conduct the components of the dosage material to the emission nozzle and, on the other hand, rotatable in order to adjust the amounts fed to the emission nozzle. A mouthpiece is preferably provided on the emission nozzle to form a widened mixing chamber. As a static mixer, the mouthpiece contributes to good thorough mixing.
