ABSTRACT:
A valve actuating apparatus for intake and exhaust valves in an internal combustion engine having an end pivot type rocker arm. The rocker arm is composed of two arms interconnected by a connecting pin so as to be foldable. A lock pin selectively brings the rocker arm into either a single rigid rocker arm condition or into a foldable rocker arm condition which absorbs the lift of the cam to rest the operation of the valve although the cam continues to rotate. The connecting pin is located so that the displacement of the rocker arm during the foldable movement thereof is minimized.
