Abstract
The invention concerns a cam follower providing a tappet having a cylindrical outer surface centered on a longitudinal axis (Y1) and adapted to slide in a housing surrounding the tappet, a pin extending between two opposite ends along a transverse axis (X1) perpendicular to the longitudinal axis, and a roller element movable in rotation relative to the pin around the transverse axis and adapted to roll on a cam. The tappet is made of a composite material integrating at least one dry lubricant released at the cylindrical outer surface when the cam follower is in operation. The invention also concerns a valve actuator for a motor vehicle, providing such a cam follower. The invention also concerns a method for manufacturing such a cam follower.
