Chamber for measuring e.g. emissions of hydrocarbons in motor vehicle, has volume balancing device, which is designed as pouch element, where chamber is directly connected charge-moderately with emission sources of object outside chamber

摘要

The chamber (7) has a volume balancing device, which is preferably designed as a pouch element (12), where the chamber is directly connected charge-moderately with emission sources (8-10) of an object in particular a motor vehicle (2), which is arranged outside the chamber. A fan (13) is provided in the chamber and is contactlessly driven by an electric motor that is arranged outside the chamber preferably by a magnet coupling of the motor arranged outside the chamber.
