Title: Switchable roller finger follower assembly

Abstract: A switchable roller finger follower for a valvetrain of an internal combustion engine. The switchable roller finger follower includes an elongated body, a cam follower, a locking pin assembly, lost motion springs and a shuttle pad assembly moving horizontally. The locking pin assembly includes a locking pin and hydraulic fluid supply channel, selectively locking and unlocking the shuttle pad assembly, allowing either a high lift or low lift profile to achieve contact with pre-determined profiles of a multi-lobe camshaft which, in turn, provides low lift or high lift operation of an associated gas exchange valve.
