Abstract
The roller finger follower employs two independent lost motion arms and a coupling device that locks both arms. A coupling element allows for changing from locked to unlocked mode. Components of the coupling element include a shuttle pin with a head, a shank and a cutout on which a rod is positioned, a coil spring which surrounds the outside diameter of the shuttle pin shank, and an end cap. By positioning the spring on the shuttle pin shank, a large spring diameter and short spring height can be used which allows for compact packaging. Also, a low spring rate is required.
