摘要： The present invention relates to a converter device adapted to being arranged in an exhaust system of a combustion engine. The converter device comprises an outer casing (1), a tubular body (4) enclosed by said casing (1), and a passage for leading exhaust gases through the converter device. In order to provide good sonic damping properties, the converter device needs to comprise a long passage for exhaust gases. In order to provide a compact converter device with a long passage, the converter device comprises at least one axial exhaust duct (13 a, b) which has a helical extent round the tubular body (4), and a radial exhaust duct (13 c, d) which has a spiral extent between a first portion (17a) of the passage, which is situated external to the tubular body (4), and a second portion (17b) of the passage, which is situated internally to the tubular body (4).

摘要： The device for silencing a flow of gas, e.g. an exhaust gas, comprises at least one acoustic chamber (l,2,3) through-flowed by gas, at least one inlet pipe (6) for leading gas into the device and at least one pipe or passage (4,12,13) interconnecting two chambers or a chamber and an exterior environment or chamber. The device includes cross-sectional area transitions between pipes or passages (4,6,12,13) and the chambers (l,2,3) so that the sound attenuation achieved by the device is high while the pressure drop across the silencer is low and that high attenuation at low characteristic frequencies of flow systems comprising the device are obtained. One or more diffusers (l0a,12a,13a) for diffusing at least part of the gas flow, e.g., at the inlet to the chambers may be included in the device. One or more monolithic bodies or catalysers may be included in the device. Devices with curved or helical passages allowing a low natural frequency and embodiments having resonance chambers attenuating at selected frequencies may be included.

摘要： The invention relates to an apparatus for absorbing the sound of a medium which flows through a tubular channel, has pulsating pressure differentials and has, at least in sections, a proportion which rotates about the longitudinal axis of the tubular channel, wherein the rotational speed of the medium is proportional, from the centre of the rotation radially to the outside, to the radial spacing from the rotational centre, characterized in that the tubular channel has at least two tubular-channel sections (1, 2) 15, wherein the first tubular-channel section (1) is arranged ahead of the second tubular-channel section (2) in the flow direction and the first tubular-channel section (1) has a predefined flow cross-sectional area (8) which is greater than the flow cross-sectional area (11) of the second tubular-channel section (2), and the ratio of the flow cross-sectional area (8) of the first tubular-channel section (1) and the flow cross-sectional area (11) of the second tubular-channel section (2) is selected in such a way that, during the passage from the first tubular-channel section (1) into the second tubular-channel section (2), the rotating medium can be accelerated in the rotational direction proportionally to the rotational speed and in the process the axial speed of the rotating medium can be reduced proportionally to the rotational acceleration of the medium.
