A first shaft is supported on bearings in the first cylinder concentric to it, with an eccentric weight attached to the first shaft. A second shaft concentric to the second cylinder is supported on bearings concentric to the second cylinder. Only one end of the housing, the other end is closed, has an end cap and the shafts are connected by helical pinions so that the helical pinions urge the weights and shafts in opposite directions from one another.
