1. current limiter (2), have:

  • - pipeline member (4) with air intake (6) and air outlet slit (8);

    The resistance element (10,32,36) of-at least one at least local perforations, described resistance element is at least partially and arches upwardPortion, cone shape or cone section shape;

    - at least one absorber (28,46);

    And- for covering perforation mouth (16) to calibrate the covering element (30) of the flow resistance of described current limiter (2),Wherein, described resistance element (10,32,36) is positioned at the inside of described pipeline member (4), and to from described air intake(6) air stream being passed to described air outlet slit (8) through described resistance element (10,32,36) applies predetermined flowingResistance,Wherein, described resistance element (10,32,36) extends at least in part on the axial direction of described pipeline member (4),Wherein, described absorber (28,46) is positioned in described pipeline member (4) and is positioned at described resistance element (10,32,36)Downstream, andThe radial dimension of described absorber (28,46) reduces in the flowing direction at least in a region.
