Abstract
A dual event valve control system for an internal combustion engine. The system includes an inner rocker arm in engagement with a valve and with a first cam, an outer rocker arm in engagement with a second cam, and a latch member which is insertable between the rocker arms, whereupon when the rocker arms do not engage the latch member, the rocker arms are free to pivot independently of one another and the valve is actuated by the first rocker arm in accordance with the lift profile of the first cam, and when the rocker arms are engaged by the latch member, the rocker arms rotate in unison and the valve is actuated by the second rocker arm in accordance with the lift profile of the second cam. A stop acting between the inner and outer rocker arms limits relative pivoting movement between the rocker arms and is effective to provide clearance between the base circle portion of its second cam and the outer rocker arm.
