Abstract:
A variable lift deactivateable valvetrain system for an engine is provided. The system includes a camshaft, a rocker shaft, a valve and at least one rocker arm rotateably connected to the rocker shaft and arranged to engage the camshaft. A connecting rocker arm is rotateably connected to the rocker shaft and is in constant engagement with the valve. The connecting rocker arm is arranged to operate in selective engagement with the at least one rocker arm to provide a variable lift deactivateable valvetrain configuration. The system further includes a low lift rocker arm having a low lift pin assembly and a high lift rocker arm having a high lift pin assembly. The low and high lift pin assemblies are arranged to selectively engage the connecting rocker arm responsive to oil pressure selectively directed to the low and high lift pin assemblies.
