摘要：A mechanism to vary the duration and lift of a valve in an internal combustionengine, wherein a lever engaging a camlobe is rotated about a fulcrum by rotation of thecamlobe; the lever possessing a member to actuate a valve; the member to engage avalve being articulated with respect to the lever, and the fulcrum possessing means todisplace the valve actuating member when the lever is rotated; the displacement of thevalve actuating member actuating a valve. Rotation of the fulcrum of the lever alters thepoint in lever rotation at which the valve actuating member is displaced to actuate thevalve, and determines the extent of that displacement, so that the duration and lift of thevlave may be varied relative to duration and lift of the camlobe.
