FUEL UNIT PUMP AND INTERNAL COMBUSTION ENGINE INCLUDING A FUEL UNIT PUMP

摘要

A fuel unit pump for an internal combustion engine includes a fuel unit pump body, a pumping plunger and a roller tappet for contacting a cam lobe of a rotatable shaft of the internal combustion engine. The roller tappet includes a roller tappet body connected to the pumping plunger, and a cam roller rotatably mounted on a cam roller carrier and defining a cam roller rotation axis. The cam roller carrier is coupled to the roller tappet body and is elastically deformable for aligning the cam roller with the cam lobe.
