    摘要： A valve operating mechanism for an internal combustion engine has a plurality of rotatable cams with different cam profiles for operating an intake or exhaust valve differently in high and low speed ranges of the engine. A plurality of rocker arms are selectively connected or disconnected for transmitting the appropriate cam lift to the valve depending on the engine speed range. The cam profiles have dampening areas (CH-CL) at the start of opening and the finish of closing of the valve. The dampening areas of the high speed cam (CH) have a smaller rate of change than the dampening areas of the low speed cam (CL) to minimize the possibility of engagement by a rocker arm with a cam for one speed while the engine is operating at another speed by another cam and rocker arm.

    摘要： Apparatus for controlling the operation of intake or exhaust valves of an internal combustion engine in which cam-driven rocker arms that operate the valves are selectively connected or disconnected for movement in unision or for independent movement in order to open and close the valves in accordance with the various modes of engine operation. Control of the valves is produced by the cooperative effect of hydraulic pressure and variable spring forces whereby more accurate valve operation over a greater number of engine operating modes is achieved.

    摘要： A valve operating device of an internal combustion engine, including a plurality of cams 3,5 on a camshaft 2 having different cam profiles corresponding to operating conditions of the engine for opening and closing an intake valve according to the operating conditions of the engine. A high-speed cam 5 has a cam lobe 5b which projects from a base circle portion 5a of the cam by a distance d2 smaller than the distance d1 by which the cam lobe 3b of a low-speed cam 3 projects from the base circle portion 3a. The cam lobe of the high-speed cam also subtends a larger angle on the base circle of the camshaft than the cam lobe of the low-speed cam.
