Patentansprüche:Patent claims: ι. Schalldämpfer für Auspuffgase mit in dem Auspuffrohr oder in dem Auspufftopf angeordneten Schraubenflächen, dadurch gekennzeichnet, daß die eine dieser Schraubenflächen eine das ganze Auspuffrohr ausfüllende mehrgängige Schraubenfläche (b) mit kleiner Steigung ist, während diese flachgängige Windung von einer oder mehreren Schraubenwindungen (d) großer Steigung durchdrungen sind, um durch den mehrfachen hierdurch erzielten Richtungswechsel der Abgase eine Schalldämpfung zu erzielen.ι. Silencer for exhaust gases with screw surfaces arranged in the exhaust pipe or in the muffler, characterized in that one of these screw surfaces is a multiple screw surface (b) with a small pitch which fills the entire exhaust pipe, while this flat turn of one or more screw turns (d) is larger Slope are penetrated in order to achieve sound absorption through the multiple changes in direction of the exhaust gases achieved in this way. 2. Schalldämpfer nach Anspruch 1, dadurch gekennzeichnet, daß eine steilgängige Schraubenfläche (d) in der Achse oder mehrere steilgängige Schraubenflächen (d) parallel zur Achse der flachgängigen Schraubenfläche (b) angeordnet sind.2. Silencer according to claim 1, characterized in that a steep helical surface (d) in the axis or several steep helical surfaces (d) are arranged parallel to the axis of the flat helical surface (b) . 3. Schalldämpfer nach Anspruch 1 und 2, dadurch gekennzeichnet, daß die steilgängigen Schraubenwindungen (d) in an sich bekannter Weise aus Metallband hergestellt sind.3. Silencer according to claim 1 and 2, characterized in that the steep screw turns (d) are made in a manner known per se from metal strip.
