Abstract:
A rocker arm assembly for a Type II valvetrain arranged for cooperation with a cylinder head includes a roller finger follower (RFF) and a lost motion with reset (LMR) hydraulic assembly. The RFF has a first end and a second end. The first end cooperates with a valve. The LMR hydraulic assembly has a hydraulic control element and a plunger. The LMR hydraulic assembly moves the plunger between a rigid position and a non-rigid position. The LMR hydraulic assembly is configured at the second end of the RFF.
