PCT No. PCT/SE83/00241 Sec. 371 Date Feb. 6, 1984 Sec. 102(e) Date Feb. 6, 1984 PCT Filed Jun. 14, 1983 PCT Pub. No. WO84/00061 PCT Pub. Date Jan. 5, 1984.Fluid damper for damping aiming movements, for instance when tracking a target. The damper comprises a substantially disc-shaped cylindrical housing (9) in which a drum-wheel (11) is supported for rotation so that an inner gap spacing (24) is provided between the drum-wheel and a slipping ring (14) integrated in the outer cylindrical wall (13) of the damper housing. Said gap spacing (24) is filled with a high-viscosity damping fluid so that a damping torque is obtained which is linearly increasing to the angular velocity for velocities up to a certain level but which are limited for velocities exceeding said level due to the fact that the slipping ring (14) starts rotating with respect to the other parts of the damper housing. The slipping ring (14) is made of a material which is temperature stable and which can be made with a high accuracy with respect to its dimensions for instance carbon-fibre reinforced epoxy resin.
