Abstract

The silencer (1) has an exhaust pipe arrangement (5) conducted through a housing (2), and an expansion chamber (3) formed in the housing. A resonator chamber (4) of a Helmholtz resonator (9) is formed in the housing. The exhaust pipe arrangement is conducted through the expansion chamber in an uninterruptible manner and exhibits a perforation (12) within the expansion chamber, where a connecting pipe (6) of the expansion chamber connects with the resonator chamber in a communicating manner. The connecting pipe is conducted through an absorption chamber (7).
