Abstract (en)
[origin: WO2009112294A1] The invention relates to a device (140) for metering at least one medium (136) for reducing pollutant levels in an exhaust system, in particular for the introduction of fuel into an exhaust line (116) for regenerating an element (130) for reducing pollutant levels in the exhaust line (116). The device (140) comprises at least one injection valve (132), in particular, a pressure-regulated injection valve (132) and at least one supply line (134) for supplying The pollutant-reducing medium (136) to The injection valve (132). At least one pressure damper (168) is provided in The supply line (134) upstream of The injection valve (132).
