| SPONTAN the surrounding hollow shaft 25 to the internal flywheel disc 6, a certain angular flexibility thus being introduced between the engine and the transmission gear. A damping arrangement 8 between the two flywheel discs smooths down Fig. 11. any torsional vibrations between the engine crank shaft and the transmission. The internal flywheel disc is provided with two diametrically opposed studs 3, each of which, by means of a pivoted link 2 is connected to one of the two opposed rotary bob weights 1 and 10. Each weight embraces, by means of ball-bearing rings, a pair of eccentrics 5, rigidly connected to the main driving sleeve 27. Fig. 13 shows an assembly of the inner flywheel disc, bob weights, eccentrics, and driving sleeve, the central projection being the flexible shaft mentioned above. 18 K/S Fig. 12.
