  "textContent": "A frequency-dependent damping valve arrangement of a vibration damper having a damping piston with at least one check valve, a control arrangement arranged coaxial to the damping piston including a control pot with a pot wall and a control piston axially displaceably arranged in the control pot that axially limits a control space. The control piston has a seal arrangement that seals the control piston relative to the pot wall including a circumferential groove formed at the control piston and a seal ring arranged therein. The seal arrangement is constructed such that this seal arrangement increases its sealing effect with rising damping medium pressure in the control space and reduces its sealing effect with falling damping medium pressure in the control space.",
