Abstract
A cam follower for operable attachment to a valve lifter assembly for use with a variable cam lobe camshaft in a variable valve timing system includes a housing with a central cavity and a mushroom head with a stem pivotably connected to the housing in the central cavity, the mushroom head having a radiused surface for contacting a cam lobe surface. The cam follower is used in combination with a variable cam surface of an axially displaceable camshaft to obtain improvements in idling speed and volumetric efficiency.
