Abstract

The present invention is directed to an improved assembly for operating at least one exhaust valve (710) and at least one intake valve (710) in a cylinder in an engine. The assembly (10) includes a rocker shaft (200), an intake rocker arm (100) pivotally mounted on the rocker shaft for operating at least one intake valve of the engine cylinder, an exhaust rocker arm pivotally mounted on the rocker shaft for operating at least one exhaust valve of the engine cylinder. The improved assembly includes a lash adjusting assembly (300) for adjusting a lash between at least one of the intake rocker arm and the at least one intake valve, and the exhaust rocker arm and the at least one exhaust valve. The improvement further includes an energy supply assembly for supplying energy to the lash adjusting assembly to operate the lash adjusting assembly. The improved assembly further includes a control assembly (500) for controlling the operation of the supply assembly in response to predetermined engine operating conditions.
