  • Patent number: 11933199
    Abstract: A switchable finger follower for a valve train of an internal combustion engine includes an outer and an inner lever, which at a first longitudinal end run pivotably relative to one another via respective bores on a common shaft. At this longitudinal end, the finger follower has a gas-exchange valve contact face on an underside. The outer lever has a pivot bearing on the underside at a further longitudinal end, and at least the inner lever has a cam running face on an upper side. The inner and outer levers are connectable to one another via at least one coupling slide, which spans a separation area between the levers. The outer and inner levers are braced relative to one another via a cam return spring, and the shaft is connected to the bore of the outer lever by an interference fit.

  • Patent number: 10260380
    Abstract: The invention relates to a locking device for a switchable valve drive component, including a first locking body and a second locking body which can be brought into engagement with one another or out of engagement in order to couple to one another or to uncouple two component parts arranged movably with respect to one another, wherein at least one of the two locking bodies has at least one curved surface. In order to increase the wear resistance of the locking device, provision is made for at least one of the two locking bodies to have a plurality of curved surfaces of which the respective curvature is described by radii of identical length having constructional center points spaced apart from one another.

  • Patent number: 9551406
    Abstract: A device for securing a support element to an actuating lever of a valvetrain of an internal combustion. The actuating lever having a socket dome to accept a socket end of the support element and a roller pocket, with the securing device seated on the socket dome, extending through the roller pocket and splitting into two arms that extend on opposite ends of a circumferential groove below the socket end of the support element.

  • Publication number: 20100307437
    Abstract: A rocker arm (1a to 1f) for a valve train of an internal combustion engine is provided having an elongate lever body (2a to 2f) formed out of sheet metal and including a first end section (3), a second end section (5) and a center section (4) formed by two spaced apart, parallel side walls (6a to 6f), having aligned axle-receiving bores (7). The first end section includes a crossbar (11a to 11f) connecting the side walls to each other and two contact surfaces (12) for a simultaneous actuation of two gas exchange valves of the internal combustion engine, and the first end section is configured substantially wider than the center section. The contact surfaces extend on the crossbar while being spaced in transverse direction from the side walls.
