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. In a second position the capillary opens outside of the mixing chamber in a suction removal space (25) surrounding the mixing chamber. Preferably the carrier gas is flowing continuously and suction removal means (26) are provided which remove the carrier gas together with the gaseous substance when the capillary opens in the suction removal space.
