FINGER FOLLOWER LOST MOTION VALVE ACTUATION SYSTEM WITH LOCATING LINK

摘要

An engine valve actuation system for an internal combustion engine is disclosed. The valve actuation system may include a longitudinally extending link member pivotally attached to an engine member. A longitudinally extending finger follower may be pivotally attached to the link member. The finger follower may include first and second contact surfaces spaced longitudinally from each other. A lost motion piston may contact the first contact surface of the finger follower and an engine valve assembly may contact the second contact surface of the finger follower. A means for receiving valve actuation motion, such as a cam follower, may be incorporated into the finger follower. A valve seating device may contact a third contact surface located on the link member, and a biasing spring may contact a fourth contact surface on the finger follower.
