ABSTRACT:
An apparatus for controlling the engagement between a cam and a push rod in an internal combustion engine for affecting operation of a valve. The apparatus includes an outer tappet engaging the cam. A central tappet is connected to the push rod and supported within the outer tappet. A tappet coupling member is disposed between the outer tappet and the central tappet. A locking element is slidable between an unlocked position where the outer tappet moves freely with respect to the central tappet and a locked position, where the outer tappet is locked to the central tappet for moving the push rod to open the valve.
