ABSTRACT:
A vibration damper comprises a housing defining a cavity; a damping mass accommodated for oscillation in the cavity between wall surfaces; and spring elements situated on two opposite sides of the damping mass. Each spring element is in engagement with the damping mass and a respective one of the wall surfaces for positioning the damping mass in the cavity. Each spring element has a shape selected to confer to the spring element a dynamic deformation behavior characterizing spherical bodies. Further, the spring elements, as viewed together, are arranged at least approximately symmetrically with respect to a central axis of the damping mass oriented parallel to the path of oscillation. The vibration damper also includes an arrangement for guiding the damping mass linearly along the path of oscillation.
