摘要：
A valve deactivation assembly includes an elongate camshaft having at least one lift lobe. The lift lobe has a lift portion and a base circle portion, and is affixed to or integral with the camshaft. A first null lobe is disposed on a first side of the lift lobe, and is affixed to or integral with the camshaft. A second null lobe is disposed on a second side of the lift lobe, and is affixed to or integral with the camshaft. A first journal bearing is disposed on the first null lobe, and a second journal bearing is disposed on the second null lobe. The journal bearings are configured for engaging a body of a deactivation roller finger follower to thereby reduce friction and wear of the roller finger follower body.
