Abstract
An exhaust silencer of a combustion engine, comprising a housing (1) that is to be connected to an exhaust pipe, through which housing the exhaust gases are arranged to be conducted and which comprises a reactive part (2) and an absorbing part (3) in the flow direction of the exhaust gases. The reactive part (2) is mainly hollow and comprises, at the inlet thereof, a first exhaust pipe (5) for feeding the exhaust gases to the reactive part (2) and, at its outlet, a second exhaust pipe (6) for directing the exhaust gases from the reactive part (2) to the absorbing part (3), both exhaust pipes (5, 6) being arranged so as to essentially extend inside the reactive part (2) of the housing. The absorbing part (3) comprises an absorbing filling element (7), which essentially fills the absorbing part (3) of the housing and, at the inlet of the absorbing part (3), is shaped so as to direct the exhaust gases to the space (8) between the filling element (7) and the inner lining of the housing (1).
