Abstract: For admixing a gaseous substance, especially an odoriferous substance, into a gas stream. The gaseous substance is fed by means of a carrier gas (23) via a line (10) to a mixing chamber (1). The line contains at least one capillary (19), which is arranged in an advancing device (9) with two defined positions. In a first position the capillary extends through an opening (6), into the mixing chamber.
