Abstract
A control arrangement for a frequency-dependent damping valve of a vibration damper having a control pot with a cylindrical pot wall and a pot base adjoining the pot wall, a control piston arranged axially displaceable in the control pot between first and second end positions. The pot base has a deformation portion produced by plastic deformation that defines the first end position. The control piston is slidingly guided at a guide bush. The deformation portion defines a trough in which the guide bush is received by a first axial end and a spring unit supported at the control piston acts on the control piston with a spring force. The guide bush has a cutout at the first axial end arranged in the trough and in which a base material of the control base is displaced by plastic deformation to form a positive engagement connection.
