Abstract:
An engine valve actuation system includes a rotatable camshaft, a first valve lifter, and a second valve lifter, structured to actuate valves in an engine in response to rotation of cams of the camshaft. The engine valve actuation system includes an anti-rotation device having a collar with a sleeve portion and a boss portion, and a bridge connector structured to couple with one of the valve lifters. Another one of the valve lifters is slidably received in the sleeve portion. The anti-rotation device reciprocates with the one of the valve lifters, and each of the valve lifters is restricted from rotation during service.
