ABSTRACT:
A device for providing additional torsional energy for a cam shaft is provided. The device includes at least one main cam lobe formed on a rotating shaft; a valve operating mechanism disposed to be engaged by the main cam lobe; and an outer cylinder encompassing the valve operating mechanism, and capable of movement that is independent of the valve operating mechanism, the outer cylinder being disposed to provide torsional energy to the rotating shaft.
