here is that undesired substantial deformations of the partition wall 11 are reliably prevented even when impact stresses and resulting pressure peaks occur inside the chambers 7 8 in dependence upon the particular conditions of the application case one can provide for a reinforcement inside the partition wall this is generally superfluous however in the case of a refinement in accordance with fig1 fig2 shows a longitudinal section through a bearing 1 essentially similar to that of fig1 along the section a a as proceeds from this drawing the restrictor duct 17 has an annular shape and extends along the outer periphery of the bearing 1 in fig3 a bearing 1 is shown whose design is similar to that of the bearing 1 of fig1 to attain a further damping maximum however an additional gap 12 2 is provided in this exemplified embodiment this gap 12 2 is likewise arranged inside the inner fitting 3 the two gaps 12 1 12 2 having essentially a symmetrical design the function of the partition wall 11 1 inside the gap 12 1 corresponds to the function of the two parts of fig1 while a second partition wall 11 2 inside the second gap 12 2 exhibits a relatively increased material strength and as a result a greater inertial mass and spring constant to damp low frequency vibrations in the range of for example 10 hz both of the two partition walls 11 1 11 2 are positioned against one surface each of the gaps 12 1 12 2 in dependence upon the pressure difference prevailing between the two chambers 7.
