ABSTRACT:
A circular-cylindrical filter muffler includes damping elements (3) arranged with their damping surfaces (11, 12) parallel to the central axis (13) of the filter muffler housing (2), which is cast as a monobloc. The damping elements are arranged in grooves (8) of the housing walls. The damping elements (3) include a damping plate (9) which encases an absorption element (10). In the assembled state the damping plates (9) form, with the coarse filter segments (15) arranged on them on the circumference of the filter muffler, a coarse filter ring which is surrounded by an annular filter (4). The advantages of the invention are, in addition to the simplified production and assembly of the components, the reduction of different components and the lower weight along with improved muffling.
