PCT No. PCT/EP89/01577 Sec. 371 Date Aug. 22, 1990 Sec. 102(e) Date Aug. 22, 1990 PCT Filed Dec. 20, 1989 PCT Pub. No. WO90/07069 PCT Pub. Date Jun. 28, 1990.A rubber block is shaped as a segment of a circular washer wherein opposite ends of the segment are surfaces against which torsional forces are applied to the blocks. A plurality of hollow ducts extend through the block and all the ducts are parallel to each other and essentially perpendicular to a main plane of the block. The main plane is perpendicular to the load bearing surfaces. The hollow ducts are intersected by cavities having cross-sectional areas larger than the corresponding cross-sectional areas of the ducts intersecting these cavities.
