Abstract: A variable valve train for gas exchange lifting valve of an internal combustion engine. The valve can be moved between open and closed positions periodically by way of a cam via a rocker arm. The variable valve train includes a camshaft having at least first and second cams which are arranged offset in the longitudinal direction of the camshaft. The first and second cams having cam contours. The valve train includes a rocker arm mounted which pivots about a rocker arm axis and is assigned to the at least one first cam via a pressure roller at its camshaft-side end and is connected to at least one lifting valve at its valve-side end, and a roller lever which is assigned to the at least one second cam at its camshaft-side end and is articulated at its other end on the rocker arm and pivots about the rocker arm axis.

Abstract: 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.

Abstract: A method for manufacturing a roller, adapted to equip a mechanical system forming a cam follower or a rocker arm. The roller is centered on a central axis and comprising: an outer cylindrical surface adapted to roll on a cam, an inner cylindrical bore adapted to receive a pin belonging to the mechanical system, and two lateral faces extending radially to the central axis. The method includes a machining step forming circular grooves that are concentric with each other on at least one of the lateral faces of the roller. The roller can be installed within a mechanical system.

Abstract: A roller tappet for a fuel unit pump of an internal combustion engine is provided with a roller tappet bore for inserting the roller tappet within the internal combustion engine. The roller tappet includes a roller tappet body having a body longitudinal axis for connecting the roller tappet to a reciprocating element of the fuel unit pump. A cam roller contacts a cam lobe of a rotatable shaft of the internal combustion engine. The cam roller is rotatably mounted to the roller tappet body around a cam roller rotation axis. The external surface of the roller tappet body is configured to allow tilting of the roller tappet within the roller tappet bore for aligning the roller tappet with respect to the cam lobe of the rotatable shaft.
