tappet

Cam-driven engine rod

A tappet is a mechanical part that transmits motion between a rotating cam and a valve or other component, typically in an engine.

Tappets transfer the cam's circular motion into the linear motion needed to open and close valves: The mechanic adjusted the tappet clearance.

Also called a cam follower or valve lifter.
