Abstract

In a spring element according to the present invention, all channels formed in the elastomer block are mutually parallel and all cavities formed in the elastomer block, too, which are intersected by said channels, are arranged like a cubic-free-centered sphere packing in reverse order. Comprising a good mechanical lateral rigidity, a spring element according to the present invention shows exceptionally good acoustic insulating and damping facilities.
