ABSTRACT:
A metering device for dispensing a medium to an environment is provided. The metering device includes a housing, a shallow metering chamber within the housing which is of planar design and is essentially closed off from the environment by wall sections, a first media inlet which is connected to the metering chamber and can be connected to a media reservoir, and a vibration mechanism which is arranged in such a manner that vibrations generated by the vibration mechanism cause pulsing changes in volume of an internal volume of the metering chamber. A wall section which is designed as an outlet wall section has metering openings so that the metering chamber is connected to the environment. The vibration mechanism forms a vibration wall section so that the metering chamber is delimited.
