摘要

Device for damping oscillation movements of a piston with respect to a cylinder, which surrounds the piston with an elastomer reinforcemenet ring, of a portable telescope for a tilting bridge on a vehicle is distinguished in that projections, in particular knobs which engage on the piston with prestressing at the inner surface of the wiping ring and bound channels which are permeable in the axial direction, are formed.
