Abstract

A particle filter (2) for filtering exhaust gas in an internal combustion engine includes a housing and a filter element. A simplified installation and/or simplified replacement of the filter element (5) and/or improved sealing of the housing (4) results if the filter element (5) is supported in an inner jacket (9), which is supported radially in an outer jacket (12) and is arranged so as to be axially movable in the outer jacket (12). The inner jacket (9) is axially supported on a ring (24), which is supported axially on a cover (22) that closes an installation opening (20) of the housing (4) via at least one supporting element (25) in order to transmit pressure forces. A muffler (1) is provided having such a particle filter (2), wherein a section of a muffler housing (3) of the muffler (1) forms the housing (4) of the particle filter (2).
