ABSTRACT:
An engine valve actuating system wherein a pair of valves is actuated by a single cam lobe. The system includes a primary rocker arm contacting the cam lobe and a secondary rocker arm or actuating plate which is contacted by the primary rocker arm and which contacts both valves and a pair of lash adjusters. The points of contact of the actuating plate with the valves and the lash adjusters are arranged in four corners with the point of contact of the primary rocker arm with the actuating plate being within a triangle defined by a line connecting the points of contact of the valves with the actuating plate and the point where lines connecting those points with the diagonally opposite points of contact of the actuating plate with the lash adjusters intersect.
