Abstract: A camshaft assembly includes a base shaft extending along a longitudinal axis. The base shaft is configured to rotate about the longitudinal axis. The camshaft assembly further includes a series of lobe packs mounted on the base shaft. The lobe pack includes a first cam lobe, a second cam, and a third cam lobe. The lobe pack further includes a barrel cam defining a control groove. The camshaft assembly further includes an actuator including an actuator body and at least one pin movably coupled to the actuator body. The lobe pack is configured to move axially relative to the base shaft between a first position, a second position, and a third position. These three lobe pack positions are used to define three discrete valve lift profiles for the intake or exhaust valves in the cylinder. The lift profiles can be different for each engine valve.

Abstract: A camshaft assembly can control the motion of the intake or exhaust valves of an internal combustion engine and includes a base shaft extending along a longitudinal axis. The camshaft assembly further includes an axially movable structure mounted on the base shaft and axially movable relative to the base shaft. The axially movable structure includes a plurality of lobe packs. Each lobe pack includes a plurality of cam lobes. The axially movable structure includes a barrel cam defining a control groove. The camshaft assembly additionally includes an actuator including an actuator body and a pin movably coupled to the actuator body between a retracted position and an extended position. The axially movable structure can move axially relative to the base shaft when the base shaft rotates about the longitudinal axis and the pin is in the extended position and at least partially disposed in the control groove.
