Abstract (en)
[origin: WO9112426A1] An installation for venting the petrol tank of a motor vehicle has an adsorption filter (AF) with an aeration line (BL) which can be closed by a controllable shutoff valve (AV). The closable aeration line makes it possible to set specific negative or excess pressures in the installation in order to test its performance. The performance data so obtained are particularly reliable.
