A follower for an engine valve train utilizes an adjustable support assembly that eliminates potential for partial engagement during operation. A lever engagement member or latch is disposed for movement on the follower body and interacts with a lever to provide a constant contact geometry. The latch may support the lever in one or more precise positions, or permit the lever to pivot free of the latch for complete lost motion, as in cylinder deactivation applications. | 2020-09-17 |
