Abstract: A variable valve system of an internal combustion engine varies an operation manner of an engine valve by controlling an angular position of a control shaft. The system comprises a stopper mechanism that determines an angular range in which the control shaft is permitted to rotate about its axis; an actuating mechanism that actuates the control shaft to rotate about its axis; and a position matching device that is practically assembly only when the actuating mechanism is being assembled. The position matching device, when assembled, restricts operation of the actuating mechanism in such a manner as to match a maximally operated position of the actuating mechanism with a maximally operated angular position of the control shaft.

Abstract: A variable valve actuation apparatus incorporates a mechanism, mounted to a control shaft, to convert rotational motion of a camshaft into pivotal motion of a valve operating cam. The mechanism has different states corresponding to varying angular positions which the control shaft is adjustable to, respectively, The mechanism is continuously variable in state to one of the different states in response to a shift of the control shaft to one of the varying angular positions. The mechanism is also operative to vary the valve operating cam, in position, relative to the associated cylinder valve in response to a shift between the different states.
