A pressure buffer stop for a vibration damper that comprises for being at least partially received in a dome bearing housing an outer contour and for coaxial arrangement on a piston rod of the vibration damper a hollow-cylindrical basic structure with an inner contour, wherein the outer contour of the pressure buffer stop comprises in at least one region for being at least partially received in the dome bearing housing a three-dimensionally structured surface.

Pressure buffer stop for a vibration damper

A vibration damper for a vehicle chassis may comprise a damper tube, a piston rod that is movable in an oscillating manner in an axial direction in the damper tube, a working piston disposed on the piston rod, and a closure package that closes the damper tube and through which the piston rod is guided. A spring element that is disposed in a region between the working piston and the closure package may comprise an annular basic body that surrounds the piston rod to form an annular chamber, an upper side facing the closure package, and a lower side facing the working piston. To reduce vibrations and noise from reaching a vehicle body, the spring element may include a lip element on the upper and/or lower side, and a spring rigidity of the lip element may be lower than a rigidity of the annular basic body.
