Muffler for the exhaust system of an automobile

Abstract

A muffler for the exhaust gas system of an automobile has a housing provided with two end walls and a circumferential wall and at least one exhaust gas channel passing therethrough. The muffler assembly also has at least two pipes, which mostly define the exhaust gas channel, which are arranged successively in the flow direction, and whose ends project into the interior of the housing. A transverse wall is provided in the housing, this wall being connected to the circumferential wall on the inside, running transverse to the exhaust gas channel and having an opening passing therethrough, said wall comprising at least two flexible wall sections in the axial direction, each having one edge adjacent to the opening, the ends of the pipes each being held at their outer side by the edge of at least one wall section.

1 . A muffler assembly for the exhaust gas system of an automobile, the assembly comprising: 
 a housing formed with two end walls and a circumferential wall and having at least one exhaust gas channel passing therethrough    at least two pipes primarily defining said exhaust gas channel, said pipes being disposed successively of each other in a flow direction and having ends projecting into an interior of said housing;    a transverse wall disposed in said housing and connected to an inside of said circumferential wall, said transverse wall extending transversely to said exhaust gas channel and having a through opening formed therein;    said transverse wall being formed of at least two wall sections, said wall sections being flexible in an axial direction and each having an edge adjoining said opening; and    said ends of said pipes being held at an outer side by a respective said edge of at least one of said wall sections.    
   
   
       2 . The muffler according to  claim 1 , wherein one of said wall sections is separated from a remaining wall region of said transverse wall by slots extending outwardly away from said opening.  
   
   
       3 . The muffler according to  claim 2 , wherein at least one of said wall sections has a region extending away from said edge and projecting away from a plane of said transverse wall.  
   
   
       4 . The muffler according to  claim 1 , wherein said edge of a respective said wall section is formed by an axially extending collar having a radially inwardly pointing side connected to an outer surface of a respective said pipe.  
   
   
       5 . The muffler according to  claim 1 , wherein each of said pipe ends has a plurality of wall sections allocated thereto, and said wall sections are distributed uniformly over a pipe circumference.  
   
   
       6 . The muffler according to  claim 5 , wherein one pipe end is respectively fixed to one pair of diametrically opposite wall sections.
