Abstract
A muffler unit (1), especially for a motor vehicle, has a two-part housing (4) with first and second housing parts (2, 3) each of a shell-like design. An outlet opening and an inlet opening (5, 6) are provided in the housing (4). An outlet bottom (12) and an inlet bottom (13) are inserted into outlet opening (5) and into the inlet opening (6), respectively. The outlet bottom (12) and inlet bottom (13) are designed each as a cover that can be inserted into outlet opening (5) and inlet opening (6).
Claims20
A muffler unit for a motor vehicle, the muffler unit comprising:
- a two-part housing comprising a first housing part of a shell-like design and a second housing part of a shell-like design, wherein an outlet opening and an inlet opening are provided in the housing;
- an outlet bottom inserted into the outlet opening as an outlet opening cover with an outlet cover portion extending in a radial direction of the outlet opening, the outlet cover portion having an outlet cover radial dimension that is greater than an outlet cover axial dimension;
- and
- an inlet bottom inserted into the inlet opening as an inlet opening cover with an inlet cover portion extending in a radial direction of the inlet opening, the inlet cover portion having an inlet cover radial dimension that is greater than an axial dimension.
An exhaust system for a motor vehicle, the exhaust system comprising:
- a muffler unit comprising a first housing part of a shell-like design and a second housing part of a shell-like design cooperating to form a housing, wherein an outlet opening and an inlet opening are provided in the housing, an outlet bottom inserted into the outlet opening as an outlet opening cover with an outlet cover portion extending in a radial direction of the outlet opening, the outlet cover portion having an outlet cover radial dimension greater than an outlet cover axial dimension and an inlet bottom inserted into the inlet opening as an inlet opening cover with an inlet cover portion extending in a radial direction of the inlet opening, the inlet cover portion having an inlet cover radial dimension greater than an axial dimension
- a feed line fluidically connected to the muffler unit for feeding exhaust gas into the muffler unit;
- and
- an exhaust line fluidically connected to the muffler unit for removing exhaust gas from the muffler unit.
A motor vehicle muffler unit comprising:
- a first housing part shell;
- a second housing part shell, the first housing part shell being connected to the second housing part shell to form a housing with an interior space and with an outlet opening and with an inlet opening;
- an outlet bottom inserted into the outlet opening as an outlet opening cover comprising an outlet cover portion extending across the outlet opening in a radial direction of the outlet opening, the outlet cover portion having an outlet cover portion radial dimension that is greater than an outlet cover portion axial dimension, the outlet cover portion defining at least one outlet pipe passage opening;
- an inlet bottom inserted into the inlet opening as an inlet opening cover comprising an inlet cover portion extending across the inlet opening in a radial direction of the inlet opening, the inlet cover portion having an inlet cover portion radial dimension that is greater than an inlet cover portion axial dimension, the inlet cover portion defining an outlet pipe passage opening;
- an outlet pipe received in the outlet pipe passage opening and extending from within the interior space, through the outlet cover portion, to an exterior of the housing;
- and
- an inlet pipe received in the inlet pipe passage opening and extending from within the interior space, through the inlet cover portion, to an exterior of the housing.
