    Abstract: In a valve drive system, a plurality of intake or exhaust valves are disposed radially in a cylinder, and the intake or exhaust valves each are driven by respective rocker arms supported for rotation on a cylinder head via a rocker pin and an intake or exhaust cam shaft having three-dimensional cams for engaging these rocker arms. A boss of the rocker arm is coupled to the rocker pin for tilting movement in a direction perpendicular to the axis of the rocker pin. The rocker arm is tiltable with respect to the rocker pin to follow the three-dimensional cam surface. The cam surface can be in line contact with the sliding surface of the rocker arm throughout its circumference.

    Abstract: A valve driving apparatus for an internal combustion engine. Each combustion chamber has a pair of intake ports and a pair of intake valves for selectively opening and closing the intake ports. Each intake valve is driven with a variable amount of valve lift. The apparatus includes a camshaft rotatably supported by the engine, cams, cam followers, a shaft moving mechanism, and brackets. Each cam lifts an associated intake valve in response to rotation of the camshaft. Each cam has a cam nose for lifting a corresponding intake valve. The radius of the cam nose varies in the axial direction. Cam followers transmit movement of the intake cams to the intake valves. The shaft moving mechanism moves the cams relative to the valves in an axial direction of the camshaft thereby varying the amount of valve lift. A lifter structure is provided that is circularly shaped to improve manufacturing accuracy. In another embodiment, the valves are oriented to increase the amount of axial movement that the cam can make, which results in greater optimization of the air intake amount.

    Abstract: A valve train for internal combustion engines utilizing an inverted bucket tappet with a pivot structure operatively disposed between the tappet and the end of the valve stem allowing the valves to be angulated with respect to each other and to the axis of the cylinder in both the transversal and the horizontal planes of the engine. Accordingly on a multi-valve engine, the valves extend radially from the associated combustion chamber to open and increase space in the center of the cylinder head for spark plugs, injectors, or pre-combustion chambers and so that the combustion chamber can be designed with a hemispherical surface, with tangentially disposed valve heads. The construction allows the use of large valves in conjunction with stronger, better-cooled valve seats and bridges. The tappets can be actuated conventionally by direct-acting overhead camshafts, by rocker arms and "T" bridges.
