Definitions
- the invention relates to a silencer with two outer half-shells and two inner half shells, in which an exhaust duct is embossed or pressed, and one on the edge the shells welded exhaust gas inlet and exhaust gas outlet, and with an angled circumferential fold.
- a silencer is known from EP 0 268 728 B1 four half shells by laser welding inside and outside are firmly connected. The complete functional interior with transverse partition walls and exhaust gas routing is in the Embossed inner half-shells. Disadvantage of the known silencer system is the complex welded connection between the individual shells.
- the object of the invention is to create a silencer of the type mentioned, in which with simple means a perfect attachment between the shells with low leakage rate is given.
- both the two outer half-shells as well as the two inner half shells together have angled circumferential fold.
- the bend ensures for adequate gas sealing. Because both inner shells with a bend included in the circumferential fold are, there is also a proper attachment between Given inner and outer shells. Nevertheless, the connection is established the circumferential fold simply.
- the common angle the individual shells in question can be made with a single one Complete the work step.
- the edges of both inner half shells are together with the edges of the outer half-shells received bent in the circumferential fold.
- edges of both inner half shells can not only be immediate in a one-step circumferential fold of the outer half-shells be recorded curved, but in a further variant of the invention also in a preliminary stage of a two-stage circumferential fold.
- the circumferential fold is preferably after angled down.
- an absorption / reflection muffler 1 of a motor vehicle includes an outer housing and an inner housing in half-shell technology consisting of two outer half-shells 2, 3 and two inner half-shells 4, 5.
- the inner housing is essentially horizontal in the outer housing arranged and forms a partition with division the total silencer volume of the outer casing in one Upper chamber and a lower chamber.
- an embossed exhaust gas duct 6 Located in the inner case an embossed exhaust gas duct 6 with an opening 17 towards the lower chamber.
- the exhaust gas inlet 7 of the exhaust gas duct 6 is circumferentially welded to the shells 2, 3, 4 and 5.
- the exhaust outlet 8 is also welded, in the present case two lower-chamber outlet pipes with two exhaust gas outlets 8 are provided.
- the upper chamber is an absorption chamber with an absorption package in the form of basalt / Cr wool or E-glass wool.
- the lower chamber is a reflection chamber with a cavity.
- Upper chamber and lower chamber can in principle also optionally as an absorption chamber with an absorption package in the form of basalt / Cr wool or E-glass wool or as Reflection chamber are executed.
- the silencer 1 has outside the areas the exhaust gas inlet 7 and the exhaust gas outlets 8 a common Peripheral edge in the form of a jointly downwards angled circumferential fold 9, which the two outer half-shells 2, 3 and the two inner half-shells 4 and 5 respectively.
- FIG 2 and 3 Examples of an embodiment of the circumferential fold 9 are shown in FIG 2 and 3 shown.
