ABSTRACT:
A valve control device for an overhead camshaft engine including a rotatable cam interconnected through a rocker to a valve mounted for reciprocal movement from an open to a closed position. The valve is normally biased toward the closed position and engages the rocker at one end, the other end of the rocker directly engaging the cam. A hydraulic brake is connected to the rocker at its other end and retards movement of the valve toward the closed position.
