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.

Apparatus for load-independent loading of a diesel soot particle filter with compressed air, in order to overcome the filter resistance when burning off the soot particles collected in the particulate filter. The device is a two-shaft, dry-running rotary compressor of the positive displacement type, which is designed as Wälzkolbenverdichter with two in a cylinder housing (1) against each other rolling piston (10, 11) in the form of a claw compressor with a small space and has an air outlet opening (13) with a adapted to achieve a small geometric compression ratio in the sense of a low internal compression matched cross-section.
