<p>A valve control system ( 15 ) in which there is provided a deactivating rocker arm ( 51 ) disposed beneath a conventional, upper rocker arm ( 27 ), and disposed within a module housing ( 17 ). The deactivating rocker arm includes a latch tab ( 63 ) and when the latch tab engages (FIG. 3 ) a latch member ( 65 ), the system operates in a normal, valve activating mode. When the latch member is in an unlatched condition (FIG. 4 ), the deactivating rocker arm pivots, compressing the valve return spring ( 41 ), which thereafter serves as the required lost motion spring, biasing the deactivating rocker arm ( 51 ) and lash compensation device ( 35 ) back toward their normal position.</p> |
