ABSTRACT:
An adjustable damping valve in a damping valve housing for a vibration damper includes a valve unit with an inlet opening in the region of a valve seat face. A valve disk is supported on the valve seat face. The valve disk is pretensioned on its rear side by a spring, wherein the pretensioning of the spring is adjustable for changing the damping force in that a supporting surface of the spring is displaceable. The supporting surface is in a working connection with a catch device, wherein the catch device can be locked by steps in that the spring which acts on the valve disk applies force to the locking bodies of the catch device in a catch profile for resiliently holding the supporting surface in a locked position.
