Abstract: The present invention provides a variable valve mechanism that varies amounts of opening and closing of a valve includes a rotating cam, a rocker arm, two lash adjusters, a hydraulic passage, and a switching mechanism. The rocker arm includes an input member and an output member. The two lash adjusters support the rocker arm so that the rocker arm can rock. The hydraulic passage includes an internal oil passage that is provided in an interior of at least one of the lash adjusters, and an arm oil passage that is provided in an interior of the rocker arm and that is connected from the internal oil passage. The switching mechanism uses a hydraulic pressure in the hydraulic passage to perform a switching between a linked state and a released state, and the switching varies the amounts of the opening and the closing of the valve.

Abstract: The invention concerns a finger lever (1) of a valve train of an internal combustion engine, said finger lever comprising two side walls (3, 4) connected through a transverse portion (2). The finger lever (1) further comprises on one end (6) of an underside (5) of the transverse portion (2), a complementary cavity (7) for a head of a support element and additionally comprises on this one end (6), a reception (8) for a coupling element (8a) for optionally coupling the finger lever (1) to a further lever (9) for achieving different cam lifts. According to the invention, the two portions (7, 8) are made in the form of a single assembled unit as a separate component. This is advantageous from the manufacturing point of view particularly if the levers (1, 9) are made of sheet metal.

Abstract: A two-step roller finger follower having a high-lift follower portion that pivots on a pivot shaft disposed on a low-lift follower portion, and having a lost-motion spring disposed between the high-lift follower and the low-lift follower to bias the high-lift follower toward the high lift cam lobe. Various bearing cups and roller shaft sleeve embodiments are shown, all of which allow for improved shaft and needle bearing arrangements. A z-stop formed by the bearing cups and/or the shaft sleeve limits the range of travel of the high-lift follower with respect to the low-lift follower. Various z-stop embodiments are provided including a non-contacting roller shaft sleeve that grounds the high-lift follower to the low-lift follower independent of the roller shaft.
