摘要： A cam follower is provided having a tappet that includes a cylindrical outer surface centered on a longitudinal axis and adapted to slide in a housing surrounding the tappet, a pin extending between two opposite ends along a transverse axis perpendicular to the longitudinal axis, a roller element movable in rotation relative to the pin around the transverse axis and adapted to roll on a cam, and lubrication channels for lubricating the pin and the roller. The cam follower further provides a support element mounted in the tappet and supporting the pin, and the lubrication channels include at least one pair of consecutive channels formed through the tappet and the support element. The invention also provides an injection pump and a valve actuator for a motor vehicle, each having such a cam follower. The invention finally provides a method for manufacturing such a cam follower.

摘要： The invention concerns a cam follower providing 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, and a roller element movable in rotation relative to the pin around the transverse axis and adapted to roll on a cam. The tappet is made of a composite material integrating at least one dry lubricant released at the cylindrical outer surface when the cam follower is in operation. The invention also concerns a valve actuator for a motor vehicle, providing such a cam follower. The invention also concerns a method for manufacturing such a cam follower.

摘要： A mechanical system forms a cam follower or a rocker arm and includes a support element, a pin extending between two opposite ends along a first axis and supported by the support element, and a roller mounted on the pin, movable in rotation relative to the pin around the first axis and adapted to roll on a cam. The support element includes a first axial abutment feature blocking the translation of a pin assembly including at least the pin, in a first direction parallel to a second axis perpendicular to the first axis. The mechanical system additionally includes an insert inserted in the support element and supporting the pin opposite the first axial abutment feature, wherein the first axial abutment feature protrudes outside a cavity delimited by the support element and receiving the pin.
