Abstract
A resilient alveolar block is provided for filtering vibrations, intended particularly to support an engine-gear box unit in a vehicle, wherein, in a rubber or elastomer block (1) cells (4, 5) are provided capable of communicating with the outside through passages for the moulding cores (respectively 2 and 3), the purpose of these cells being to obtain a very low constant stiffness of the block. The cells and their respective passages are distributed in identical superimposed layers, with two adjacent layers being offset by 90.degree. through rotation about the axis of the block so that, seen in projection, the spherical cells may be narrowly interleaved.
