<p>The gun contains a housing, pressure container with the components of the material, a delivery nozzle and a metering device which is constructed as a nozzle needle for the delivery nozzle. The metering device (7) contains a hollow needle (31) and a metering needle (32) which is arranged in the hollow needle so that coaxial material streams which flow into one another can be delivered at the delivery nozzle (6). …<??>With respect to the hollow needle (31), the metering needle (32) is on the one hand displaceable in order to be able to feed the components of the material to the delivery nozzle (6) and on the other hand rotatable in order to be able to set the amount fed to the delivery nozzle (6). …<??>A mouthpiece (81) which forms a widened mixing chamber and whilst acting as a static mixer contributes to good blending can be plugged onto the delivery nozzle (6). …<IMAGE>… </p> |
