Beschreibung
Zusammenfassung:	In order, in mixing devices for at least two flowable, plastic-forming, in particular foam-forming, reactive components, to eliminate, using technically simple and reliably operating means, the presence of air in the mixing chamber (20) at the start of the shot, a multi-component nozzle (1) is combined with a mixing chamber (20) which connects with the outlet opening (17) of said multi-component nozzle (1) and in which a slide (21) is guided, which slide, during the mixing operation, assumes a position for releasing the mixing chamber (20), but at the start of merging of the reactive components fills the mixing chamber (20) and seals the outlet opening (17) of the multi-component nozzle (1) in a gas-tight manner.
