Title:

FILTER MUFFLER FOR AN EXHAUST GAS TURBOCHARGER OF AN INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/2019/137854

Kind Code:

A1

Abstract:

The invention relates to a filter muffler (10) comprising a front element (11), a rear element (12), and a plurality of damping elements (20) which are arranged between the front element (11) and the rear element (12). The damping elements (20) are arranged radially about a central axis (16) of the filter muffler such that a flow channel (30) is formed between each pair of adjacent damping elements. The respective downstream ends (22) of the damping elements (20) each have a diffuser element (23) which has a downstream tapering. An angle α between two opposing sides of the diffuser element (23) is selected from a range of 1° ≤α ≤ 8°.
