    Abstract: A valve control system (13) for an internal combustion engine including a cylinder head (11), and a poppet valve (15). A camshaft (21) has a first cam profile (25) and a second cam profile (27), and a rocker arm assembly (29) includes a first cam follower (49) and a second cam follower (61) engageable with the second cam profile (27). The poppet valve (15) is disposed toward a first axial end of said rocker arm assembly (29), and there is a first fulcrum surface (39) toward a second axial end of the rocker arm assembly. The first and second axial ends of the rocker arm assembly are oppositely disposed about the first (49) and second (61) cam followers, and a first lash compensation device (83) is operably associated with the cylinder head and includes a first plunger (97) in engagement with the first fulcrum surface (39). The valve control system (13) is characterized by the rocker arm assembly (29) defining a second fulcrum surface (59) disposed axially between the first fulcrum surface (39) and the cam followers (49,61). A second lash compensation device (85) is operably associated with the cylinder head and includes a second plunger (99) in engagement with the second fulcrum surface (59) of the rocker arm assembly (29). Each of the first (83) and second (85) lash compensation devices is selectively switchable between a latched condition (FIG. 1) and an unlatched condition.

    Abstract: The current invention provides an inexpensive variable valve mechanism that includes a first intervening member which rotates a small angle rotation about an axis of a support shaft by being pressed by a rotating cam and a second intervening member which lifts a valve by making a small angle rotation about an axis of the support shaft together with the first intervening member thus pressing a cam corresponding part of a rocker arm. The variable valve mechanism further includes a control shaft which is provided concentrically with the support shaft, a slider which moves with the control shaft, a slanted part which is formed diagonally relative to the slider's movement direction and is in contact with the slider, and a relative rotation angle control device which varies the relative rotation angle of the first intervening member and the second intervening member by pressing the slanted part in a direction substantially perpendicular to the slider's movement direction by moving the slider together with the control shaft, thus varying the valve's lift and operating angle continuously.

    Abstract: A shim attaching and detaching surface has a sectional portion with a smaller diameter than a base circle of a cam surface in a state in which the shim attaching and detaching surface of a cam is located on a tappet roller, and therefore the tappet roller and an arm member can be moved upward. Since an inner side of a top surface of a tappet guide is inclined, if the arm member is tilted along this inclination, one end of the arm member can be raised, and a clearance is formed in a space from a tappet shim. Accordingly, by inserting a slim plate-shaped or rod-shaped jig 128 from the clearance, the tappet shim 37EX can be attached and detached.

    Abstract: A valve system has a piston mounted in a cylinder in one of first and second rocker arms and is adapted to be forced by a return spring, and an engagement projection formed in the other one of the first and second rocker arms and is adapted to abut the piston to cause both of the first and second rocker arms to move in conjunction with each other. The return spring is disposed eccentrically with respect to the piston in such a direction as to get away from the engagement projection. Therefore, it is possible to ensure a sufficient stiffness of a power transmitting section of the valve system and a sufficient valve lift.

    Abstract: An overhead camshaft internal combustion engine is disclosed having a valve mechanism which comprises an intake or exhaust poppet valve 14 having a valve stem operated by two cams 16 and 18 mounted for rotation about a common axis. A first rocker 20 mounted on a pivot shaft 26 acts between the first cam 16 and the valve 14. A second rocker 28 is mounted in the engine on a fixed pivot shaft 30 and acts between the second cam 18 and the pivot shaft 26 of the first rocker 20, to raise and lower the pivot point 26 of the first rocker 20 cyclically in synchronism with the rotation of the second cam 18.
