Abstract
A rocker arm assembly includes a U-shaped rocker arm defined by a bottom wall and, two side walls depending upwardly therefrom where the side walls each have a central axle opening to support a transversely extending roller axle. A roller for rolling against a cam is rotatably supported on the roller axle through a roller bearing. The bottom wall of the rocker arm has a centrally located opening providing clearance for rotation of the roller and a spherical socket at a first end of the rocker arm to interface with an upper rounded end of a hydraulic lash adjuster. An oiling channel is provided along the bottom wall extending from the spherical socket, towards the roller, to terminate at the centrally located opening for channeling oil expelled from the hydraulic lash adjuster, wherein reciprocation of the rocker arm flings oil from the channel to the roller and roller bearing for lubrication.
