Abstract: A phase shift device utilized for the camshaft sprockets in a chain control device for an engine having separate camshafts for intake and exhaust valves in an internal combustion engine. A device supporting one or a pair of idler sprockets is shiftable, either pivotally or longitudinally to vary the chain path between a driving and a driven camshaft sprocket in such a way as to vary the phase of the driven sprocket relative to the driving sprocket. This device comprises a bracket which carries at least one idler sprocket and is either pivotally or longitudinally shiftable to vary the phase thus facilitating proper chain control.

Abstract: Several embodiments of variable valve timing arrangements for double overhead camshaft engines having cylinder banks disposed at an angle to each other. In each embodiment, the variable timing is achieved by means of a pair of idler sprockets that are disposed between the camshafts of the respective cylinder banks and which are operated in unison so as to rotate the camshafts in an appropriate direction to achieve simultaneous valve timing adjustment of all camshafts in the desired relationship. In addition, an improved arrangement is disclosed for driving the camshafts of one cylinder bank from those of another cylinder bank.

Abstract: A camshaft drive arrangement for an internal combustion engine including an improved arrangement for adjusting the valve timing during running of the engine. The timing is adjusted by means of a pair of pulleys that are engaged with opposite flights of a timing belt or chain and which are carried by a pivotally supported adjusting lever. The pivotal position of the lever and, according, the valve timing is altered in response to sensed engine conditions.

Abstract: A longitudinally slidable cam shaft means for use with an automotive power system having improved efficiency and low pollution characteristics. The drive motor operates only when power to the wheels is desired and includes variably opening valves controlled by the cam shaft means. The axially sliding cam shaft controls the valves which may be opened by varying amounts to control the speed and direction of rotation of the drive motor. Regenerative braking is provided by the drive motor and by reversing the direction of rotation of the cam shaft, the valves act to send compressed gas to the combustion chamber.
