ABSTRACT:
A device is proposed which enables a cam controlling an internal combustion engine valve to be moved relative to its driving shaft. A drive member is rotatable with a driving shaft, and a cam for co-axial rotation relative to the driving shaft. An intermediate member is mounted in a support for rotation so as to rotate eccentrically with respect to an axis of the driving shaft. The support is held for movement within a plane perpendicular to the shaft axis. A control rod is drivingly associated with the support and driven by an actuator.
