ABSTRACT:
A centrifugal force governed mechanism for continuously controlling valve timing events of internal combustion engines. An outer-hub being coaxially interfaced in a journally oscillating relationship with an inner-hub and through a center bore, longitudinally mounted onto the camshaft and synchronously driven by the crankshaft. A plurality of parallel sided cavities radially placed within one side of the inner-hub and leading outward through the journaling periphery thereof into each counterpart within the outer-hub. A guided sliding weight within each cavity of the inner-hub provides the phasing control between the inner and outer-hub members. When the centrifugal force overcomes the camshaft torque and tension of the return-spring, each weight is expelled radially outward into each correspondingly placed cavity within the outer-hub. In an alternate embodiment, the centrifugal force and camshaft torque together overcome the return-spring tension. The phasing ramp of the cavity within the outer-hub and the opposite guiding side of each corresponding cavity within the inner-hub, cooperatively with said weights, change the phased angular relationship between the camshaft and the crankshaft.
