CAM FOLLOWER, INJECTION PUMP AND VALVE ACTUATOR COMPRISING SUCH A CAM FOLLOWER, AND MANUFACTURING METHOD

摘要

The invention concerns a cam follower (1) comprising a tappet (10) having a cylindrical outer surface (14) centered on a longitudinal axis (Y1) and adapted to slide in a housing (2) 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 (10) is made of a composite material integrating at least one dry lubricant released at the cylindrical outer surface (14) when the cam follower (1) is in operation. The invention also concerns an injection pump and a valve actuator for a motor vehicle, each comprising such a cam follower (1). The invention also concerns a method for manufacturing such a cam follower (1).
