Abstract
The present disclosure provides a high-pressure fuel pump including a barrel unit, a plunger, and a camshaft assembly having an eccentric cam lobe including a surface of the lobe. A follower is provided between the plunger and the surface of the lobe of the camshaft assembly to facilitate translation between the rotational movement of the camshaft assembly to axial movement of the plunger. The follower includes arcuate surfaces configured to mate with corresponding arcuate surfaces of the lobe of the cam shaft assembly and the plunger, respectively.
