The invention relates to a filter or catalytic-converter device in which the greatest possible amount of a fluid medium in a housing is brought into contact with the surface of a device, in the housing, with openings in the direction of flow of the medium. The device comprises fixed parts (24; 124; 224) and moving parts (22; 122; 322), and the fluid medium is guided in such a manner that it flows alternately through fixed parts (24; 124; 224) and moving parts (22; 122; 322) of the device. The invention also relates to a catalytic- converter through which a fluid medium, preferably gas, is brought into contact with a catalytic substance, this medium flowing through a carrier structure (409; 425; 439) for the catalytic substance. The carrier structure (409; 425; 439) comprises grids or perforated plates which carry the catalytic substance and through which the fluid medium flows, and a drive device (408; 432) is provided which moves the grids or perforated plates at right angles to the direction of flow of the fluid medium.
L'invention concerne un filtre ou un convertisseur catalytique dans lequel la plus grande quantité possible d'un fluide se trouvant dans un corps est mis en contact avec la surface d'un dispositif se trouvant dans le corps, présentant des ouvertures dans le sens d'écoulement du fluide. Le dispositif comprend des parties fixes (24; 124; 224) et des parties mobiles (22; 122; 322), et le fluide est guidé de sorte qu'il s'écoule, alternativement, à travers les parties fixes (24; 124; 224) et les parties mobiles (22; 122; 322) du dispositif. L'invention concerne également un convertisseur catalytique à travers lequel un fluide, de préférence un gaz, est mis en contact avec une substance catalytique, le fluide s'écoulant à travers une structure (409; 425; 439) portant la substance catalytique. La structure (409; 425; 439) portant la substance catalytique comprend des grilles ou des plaques perforées qui portent la substance catalytique et à travers lesquelles s'écoule le fluide, et un dispositif d'entraînement (408; 432) déplace lesdites grilles ou plaques perforées perpendiculairement au sens d'écoulement du fluide.
