Abstract

A valve lifter of the roller type formed of a lightweight metal preferably aluminum or magnesium alloy. A roller formed of a wear resistant ceramic material is rotatably secured to the valve lifter. The wear/bearing surfaces of the valve lifter are impregnated with a solid film lubricant to provide reduced friction during operation.
