Abstract
A roller cam follower for an internal combustion engine. The cam follower includes a roller assembly consisting of an insert member formed of a conformable plastic material and an axleless roller received in a cavity formed in the insert, the material of the insert closely conforming to the contour of the roller. Various adaptations of the inventive cam follower structure are shown; including a light weight mechanical valve lifter, a hydraulic lash adjuster, a rocker arm and a mechanical direct acting tappet; all of which include means for conducting oil from the exterior of the cam follower to the roller cavity.
