Abstract
A valve system for an engine includes two cams each having a follower, a summation lever coupled to the followers, a lash adjuster, a valve actuating rocker pivotably coupled to the summation lever and resting on the lash adjuster, a control spring urging the summation lever to compress the lash adjuster, a stop limiting an expansion of the control spring, a bore, a plunger which moves in the bore, and an abutment surface. The control spring acts on the summation lever via the plunger. A plunger end engages with the summation lever. A point of contact between the plunger and the summation lever is displaced in a direction transverse to a plunger axis during a pivoting movement of the summation lever. A plunger shoulder is arranged a distance from the plunger end to contact the abutment surface to limit a plunger displacement in a direction compressing the lash adjuster.
