    摘要： The cam follower roller device comprises a body 12, a roller 14, and a shaft 16 mounted on the body 12 and comprising an outer seat for mounting the roller to rotate. The roller comprises an inner surface 14a radially surrounding the seat and is mounted able to rotate with respect to the shaft. The outer seat of the shaft and/or the inner surface 14a of the roller comprise a plurality of cavities. The ratio of the sum of the surfaces areas of the cavities to the total surface area of the outer seat, or of the inner surface, in which the cavities are formed is between 2% and 40%. The cavities have a depth between 0.5 μm and 5 μm.

    摘要： The invention concerns a cam follower including 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 (Y1), a roller element movable in rotation relative to the pin around the transverse axis (X1) and adapted to roll on a cam, and an antirotation member for preventing a rotation of the tappet around the longitudinal axis (Y1) in the housing. According to the invention, the antirotation member is one of overmoulded onto the tappet and the tappet is overmolded onto the antirotation member. The invention also concerns an injection pump for a motor vehicle, each having a cam follower. The invention also concerns a method for manufacturing a cam follower.
