    摘要: A valve actuating arrangement for an internal combustion engine valve train which has, for a pair of valves (34, 36 or 35, 37) a respective rocker member (31, 32, 33, 34) for each valve of the pair and a single actuating rod. Each rocker member is simultaneously movable under the action of the single actuating rod for simultaneous actuation of each valve of the pair thereof by a respective rocker member. The actuating rod may be a cam follower (22 or 24) movable longitudinally under the action of a cam profile (18 or 20) provided on a camshaft (12). Each rocker member may be mounted on a respective shaft, (38, 39, 40, 41) the shafts being inclined such that each rocker member has a shaft axis substantially perpendicular to the longitudinal movement of the cam follower and also substantially perpendicular to the axis of the respective valve. Typically, in a valve actuating system for a pair of inlet valves and a pair of outlet valves, the system comprises for each pair of valves a respective such valve actuating arrangement.

    摘要: A valve driving apparatus for an internal combustion engine. Each combustion chamber has a pair of intake ports and a pair of intake valves (18) 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 (10) rotatably supported by the engine, cams (11), cam followers (25), a shaft moving mechanism, and brackets (23). 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 (25) transmit movement of the intake cams to the intake valves. The shaft moving mechanism moves the cams (11) relative to the valves (18) 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.
