ABSTRACT:
An engine valve control mechanism is disclosed in which the eccentricity of an intermediate member can be varied by a pivotable support and a valve lift of a cylinder valve is varied in response to the varying eccentricity such that a reduced valve lift is produced during operation with the intermediate member held eccentric with a driving shaft which drives, via the intermediate member, a cam which actuates the valve.
