Abstract (en)
[origin: WO0181734A1] An automotive exhaust silencer system (1) consisting of exhaust silencers (2, 3) and an actuator (4) for modifying the flow resistance of the waste gas flowing therethrough by modifying the damping characteristics . The actuator (4) is provided with an inlet (6) and two outlets (7,8) in a branch-off (5). Each outlet (7 or 8) is connected to a silencer (2 or 3) by means of a conduit (9 or 10) and the flow diameter (D) of the inlet (6) can be modified by the actuator.
