摘要： 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.
