Apparatus for dosing gaseous and/or vaporous substances An apparatus for dosing gaseous and/or vaporous substances, in particular for generating varying scents, includes a multitude of packaged storage containers ( 1 ) from which different gases and/or vapors are driven out by a carrier medium. On their inlet sides, the storage containers are connected to a common carrier medium manifold ( 13 ) via a shut-off device ( 4 ) assigned to each storage container that can be actuated, and on their outlet sides to a joint homogenization chamber ( 8 ). Both the carrier medium manifold and the homogenization chamber are connected to a carrier medium source using a regulating valve ( 5, 9 ). Check valves ( 6, 7 ) are integrated in the gas passages to the storage container and from the storage container to the homogenization chamber. A dosing apparatus designed based on this principle is characterized by low space requirements and materially separate volume flows that can be exactly timed and dosed.
