US07934476B2 Valve-actuating system for an internal combustion engine, engine incorporating same, and method of using same 有权
用于内燃机的阀致动系统，并入其的发动机及其使用方法

Valve-actuating system for an internal combustion engine, engine incorporating same, and method of using same
Abstract:
A valve-actuating system for an engine, in which left and right rocker arms are moved in axial directions of a rocker arm shaft to one of a first operating position in which the rocker arms are allowed to abut on first cams, and a second operating position in which the rocker arms are allowed to abut on second cams. The rocker arm shaft is slidably supported by an engine frame so as to be movable in the axial directions thereof. During an engine operation, when the left and right rocker arms are about to be selectively moved to one of the operating positions, the rocker arm shaft is moved in advance to the same side of the selected one of the operating positions, and thereafter the left and right rocker arms are moved to the selected one of the operating position.
Abstract(Chinese):

一种用于发动机的阀致动系统，其中左和右摇臂在摇臂轴的轴向方向上移动到第一操作位置中的一个，其中摇臂被允许抵靠第一凸轮，第二操作 使摇臂可以抵靠第二凸轮的位置。 摇臂轴由发动机框架可滑动地支撑，以便能够沿其轴向移动。 在发动机操作期间，当左和右摇臂将要选择性地移动到其中一个操作位置时，摇臂轴预先移动到所选择的一个操作位置的相同侧，然后向左移动 并且右摇臂被移动到所选择的一个操作位置。
