ABSTRACT:
The invention provides a finger follower body defining a downwardly opening dome at one end, the dome having a seat which is a spherical band having a center and being concentric about a center line. A downwardly facing and downwardly convex valve contact surface is provided at the other end of the follower, and a pair of side walls define openings aligned about an axis. The openings are positioned in the side walls so that a bearing mounted in the openings will be essentially above a first imaginary line drawn between the center of the spherical band and the valve contact surface. The center line converges with another imaginary line drawn through the axis and at right angles to the first imaginary line. A finger follower incorporating the body is also provided.
