摘要:
A two-step finger follower rocker arm assembly including a follower body having a socket at a first end for engaging a hydraulic lash adjuster and a pad at an opposite end for engaging a valve stem. A passage through the follower body in the direction of actuation by an engine cam lobe is slidingly receivable of a slider member for variably engaging a central cam lobe, preferably a high-lift lobe. A latch member driven by a piston selectively locks the slider member to the follower body such that the follower follows the motion of the central cam lobe. When the latch member is disengaged from the slider member, the slider member slides within the follower body. The body is provided with a stud extending from an upper surface thereof and formed as an extension of the passage for supporting the slider over a greater length thereof such that a counter-torque moment on the slider in the passage is reduced.
