Abstract

Es wird eine Vorrichtung zur katalytischen Reinigung von Abgasen, insbesondere von Brennkraftmaschinen, an­ gegeben, bei der ein in einem Gehäuse (1) angeordneter Ka­ talysatorträger (4) gegenüber dem Gehäuse (1) durch ein gewell­ tes Teil (5) aus temperatur- und korrosionsbeständigem Me­ talldraht abgestützt ist. Dabei ist die Wellung des Tei­ les omegaförmig ausgebildet derart, daß im eingebauten Zustand die aufeinander zugerichteten Flankenteile der jeweils benachbarten Wellenberge (6) und Wellentäler (7) anei­ nander liegen. It becomes a catalytic cleaning device of exhaust gases, in particular from internal combustion engines given in which a Ka arranged in a housing (1) Talysatorträger (4) opposite the housing (1) by a wave tes part (5) made of temperature and corrosion resistant Me tall wire is supported. Here is the curl of the Tei les omega-shaped such that in the built-in Condition the mutually facing flank parts of the each adjacent wave crests (6) and wave troughs (7) anei lie next to each other.
