Abstract:
1. A system that operatively actuates a plurality of valves that provide for ventilation to at least one cylinder of an internal combustion engine, in which system: an axial cam that comprises a first contact face and a second contact face and a central cavity is both of, mounted and driven, to rotate about an axis; the central cavity borders the first contact face and proceeds between it and the axis to an open end, the first contact face facing axially away from the open end; a plurality of followers are mounted at respective azimuths about the axis, each follower driven in one axial direction by the first contact face and in the other axial direction by the second contact face; the followers are driven by the axial cam at timings distinct from one another; each follower communicates its driven position by an operative linkage that proceeds immediately from that follower's contact with the first contact face, through the central cavity, and out through the open end; and each follower by so communicating its driven position operatively actuates at least one valve.
