US 2013/0276418 A1 · EXHAUST-GAS TREATMENT DEVICE

Abstract

An exhaust-gas treatment device (1) for an exhaust gas system of an internal combustion engine, in particular of a motor vehicle, includes a housing (2), the jacket (3) of which encloses an accommodating space (5) in the circumferential direction, at least one exhaust-gas treatment element (6), which is arranged in the accommodating space (5), and a bearing layer (7) made of an elastic bearing material, which bearing layer encloses the at least one exhaust-gas treatment element (6) in the circumferential direction and which lies radially against at least one exhaust-gas treatment element (6). An insulating layer (8), made of a thermally insulating, deformation resistant/compression resistant insulating material, encloses the bearing layer (7) in the circumferential direction within the jacket (3).

Dependent claims

An exhaust gas treatment device for an exhaust system of an internal combustion engine, the exhaust gas treatment device comprising:

a housing comprising a jacket which encloses an accommodation space in a circumferential direction;
an exhaust gas treatment element arranged in the accommodation space;
a bearing layer of an elastic bearing material, which encloses the exhaust gas treatment element in the circumferential direction and radially lies against the exhaust gas treatment element;
an insulating layer, of a thermally insulating, deformation resistant/compression resistant insulating material, which encloses the bearing layer in the circumferential direction within the jacket, the insulating layer being configured to be deformation resistant/compression resistant and to transmit radially orientated pressure forces between the jacket and the bearing layer, which the bearing layer introduces onto the exhaust gas treatment element.

An exhaust gas treatment device for an exhaust system of an internal combustion engine, the exhaust gas treatment device comprising:

a housing comprising a jacket which encloses an accommodation space in a circumferential direction;
an exhaust gas treatment element arranged in the accommodation space;
a bearing layer comprising elastically deformable bearing material extending about the exhaust gas treatment element in the circumferential direction within the jacket and bearing against a radial outer surface of the exhaust gas treatment element;
an insulating layer comprising thermally insulating and deformation resistant/compression resistant insulating material extending about the bearing layer in the circumferential direction within the jacket, the insulating layer transmitting forces with a radial direction component between the jacket and the bearing layer, which the bearing layer introduces onto the exhaust gas treatment element.
