US 2017/0321581 A1 · EXHAUST MUFFLER FOR LONGITUDINAL INSTALLATION IN A VEHICLE

Abstract

An exhaust muffler, for longitudinal installation in a vehicle, includes a muffler housing (28) elongated in the direction of a longitudinal axis (G) of the housing. The muffler housing (28) has a housing jacket (30) and two front walls (32, 34), which are arranged, with respect to the direction of the longitudinal axis (G) of the housing, at spaced locations from one another. The front walls (32, 34) and the housing jacket (30) define a muffler interior space. At least one inlet pipe leads into the muffler interior space and at least one outlet pipe leads out of the muffler interior space. The housing jacket includes at least one predetermined deformation area (64, 66) including at least one wall area (68, 70), not parallel to the housing longitudinal axis (G), provided at the housing jacket (30).
