Zusammenfassung: | A two-step roller finger follower for shifting between high-lift and low-lift valve modes includes a body having side members defining coaxially disposed shaft orifices, a pallet end, a socket end, a slider arm aperture, and a latch pin channel. The socket end is mountable to a lash adjuster, and the pallet end is matable with a valve stem. A slider arm for engaging a high-lift cam lobe is disposed in the aperture, is pivotably mounted to the body, and includes a slider tip for engaging a latch pin having a nose section. A spool-shaped roller is adapted to follow the surface motion of low-lift cam lobes. The axis of the latch pin intersects a radius extension of the slider arm at an angle of less than 180° such that the latch pin is prevented from accidentally locking the slider arm in its lost-motion position. |
