  • Lifter providing improved cam lobe lubrication
    Patent number: 11002160
    Abstract: A cam follower assembly includes a cam roller, and a generally cylindrical body having an outer peripheral surface configured to be reciprocally slidable within a bore of an engine component. The cam roller is rotatably mounted on the body and configured to engage with a cam lobe on a camshaft of the engine. The cam lobe is operative to drive the body to a position at which the cam follower assembly causes one of opening of a valve or actuation of a fuel injector of the engine. A groove is formed in the body inset from the outer peripheral surface and extending axially along the outer peripheral surface parallel to the longitudinal axis of the body and aligned with an axial median plane of the cam roller and the cam lobe.
