Abstract

A squeeze film damper is provided, which includes a bearing cartridge (6), a housing (4), in which the bearing cartridge (6) is accommodated, and a squeeze film in a gap (22) between the housing (4) and the bearing cartridge (6) for producing a damping force directed opposite a circulating radial exciter force, which is generated by an imbalance retained in the bearing cartridge (6).
