Abstract

A vibration absorber (1) with radially acting hydraulic damping has a bearing core (2). A bearing cage (4) radially surrounding the bearing core (2) and an elastomer body (18) resiliently connects the bearing core (2) and the bearing cage (4). An outer sleeve (24) radially surrounds the elastomer body (18) for connection to an absorber mass (40). At least two working chambers (28) to be filled with a damping fluid are formed in the elastomer body (18). The working chambers (28) are connected fluidically to one another by means of a dimensionally stable fluid duct (26).
