Muffler And Method For Manufacturing Same

An internal combustion engine exhaust system muffler (1) has a housing (2) within which two chambers (3) are formed with an inner panel (4) arranged therebetween. The inner panel (4) has at least one collar (8) at the edge, which has an outer side (9) facing the housing (2), and wherein the housing (2) has, on an inner side (11), in the area of the inner panel (4), at least one contour (12), which faces the collar (8) and with which the collar (8) is in contact. Reduced noise generation, reduced wear as well as prolonged service life can be achieved with the outer side (9) of the collar (8) forming a cone structure (10) in profile and the contour (12) of the housing (2) forms a cone structure seat (13) with a complementary cone profile and with which the cone (10) is flatly and non-positively in contact. 本发明涉及种用于内燃机的排气系统的消音器（1），其配备有壳体（2），其中形成至少两个腔室（3），在壳体（2）中的腔室（3）之间设置内部基础（4），其中内部基础（4）具有至少个边缘侧卡圈（8），其具有面向所述壳体（2）的外侧（9），并且其中壳体（2）在其内侧（11）上的内部基础（4）区域中具有至少个面向所述卡圈（8）的轮廓（12），卡圈（8）抵靠该轮廓。当卡圈（8）的外侧（9）在侧面形成圆锥体（10）时，并且当壳体
