Abstract

Vorrichtung zum lastunabhängigen Beaufschlagen eines Diesel-Rußpartikelfilters mit Druckluft, um beim Abbrennen der im Partikelfilter gesammelten Rußpartikel den Filterwiderstand zu überwinden. Die Vorrichtung ist ein zweiwelliger, trockenlaufender Rotationsverdichter vom Typ Verdrängermaschine, der als Wälzkolbenverdichter mit zwei sich in einem Zylindergehäuse (1) gegeneinander abwälzenden Kolben (10, 11) in Form eines Klauenverdichters mit kleinem Bauraum ausgestaltet ist und weist eine Luftaustrittsöffnung (13) mit einem zum Erzielen eines kleinen geometrischen Verdichtungsverhältnisses im Sinn einer geringen inneren Verdichtung angepassten Querschnitt auf.
