Abstract:
The finger follower has an inner and outer body and a torsional lost motion spring positioned at its lash adjuster end of the outer body. The torsional lost motion springs have a short leg that abuts the outer body and a long leg that contacts the inner body. The torsional spring is located above the pivot point of the finger follower so as to provide a low mass moment of inertia and to reduce the weight over the valve stem end of the follower.
