Abstract:
1. A muffler for an intake tract of a combustion engine, comprising: a resonator housing having a shape which corresponds to a part segment of an annular body and is formed with a continuous cross section; and a resonator slide-in unit having a shape which corresponds to a part segment of an annular body, is formed with a continuous cross section and which is slid into the resonator housing in a part circle-like movement, the resonator slide-in unit having a plurality of annular ribs spaced apart along an outer circumference of the resonator slide-in unit and a plurality of radial ribs spaced apart along the outer circumference, the plurality of annular ribs intersecting the plurality of radial ribs to form a plurality of resonator volumes, and the resonator slide-in unit is formed along an arc to have a first radius at a first side and a second radius at a second side, the second side opposite the first side, the second radius larger than the first radius and the plurality of resonator volumes increase in volume from the first side to the second side, the resonator slide-in unit having a first portion and a second portion that cooperate to define the resonator slide-in unit, the first portion and the second portion each including the first side and the second side, and the resonator slide-in unit extends continuously from a first end of the resonator housing to a second end of the resonator housing.
