摘要： In a variable valve opening property internal combustion engine, a roller link (22) is provided with a cam roller (31) at a free end thereof which engages a cam (3) of a camshaft (4) and a pressure surface (47) of a spring device (41). The roller link is pivotally supported by a bearing portion of a control link (21) which can be adjusted in position by using an actuator (14). The roller link is additionally provided with a roller shaft (31) that engages a slipper surface of a rocker arm (6). The pressure surface of the spring device may be contoured or otherwise inclined so that the direction of action of the spring device on the cam roller can be directed in an optimum direction irrespective of the adjusted position of the pivot point of the roller link.
摘要翻译：在可变开阀特性内燃机中，滚子连杆（22）在其自由端设有与凸轮轴（4）的凸轮（3）和压力表面（47）接合的凸轮滚子（31）的弹簧装置（41）。滚子连杆由控制连杆（21）的轴承部枢转地支撑，所述控制连杆可通过使用致动器（14）在位置上进行调节。滚子连杆还设置有与摇臂（6）的拖鞋表面接合的滚子轴（31）。弹簧装置的压力表面可以是轮廓或其它方式倾斜的，使得弹簧装置在凸轮辊上的作用方向可以被引导到最佳方向，而不管滚子连杆的枢转点的调整位置如何。

摘要： Provided is a variable valve lift internal combustion engine including a control shaft pivotally supported by a cylinder head via a pivot arm pivotally supported by the cylinder head so as to able to move angularly around a rotational center line extending in parallel with an axial line of the control shaft, a power transmitting member supported by the control shaft, an actuator for causing an angular movement of the control shaft around the rotational center line via the power transmitting member and a control arm having a base end pivotally supported by the control shaft and a free end interposed between a cam lobe of an engine camshaft and a part of a rocker arm. The lift of the engine valve can be varied by angularly moving the control shaft around the rotational center line and moving the base end of the control arm.
摘要翻译：提供一种可变气门升程内燃机，其包括控制轴，所述控制轴通过由所述气缸盖枢转地支撑的枢转臂枢转地支撑在气缸盖上，以便能够围绕与所述气缸盖的轴线平行延伸的旋转中心线成角度地移动控制轴，由控制轴支撑的动力传递部件，用于经由动力传递部件使控制轴绕旋转中心线的角度运动的致动器，以及具有由控制轴可枢转地支撑的基端的控制臂，自由端置于发动机凸轮轴的凸轮凸缘和摇臂的一部分之间。发动机气门的升程可以通过围绕旋转中心线的角度地移动控制轴并且移动控制臂的基端来改变。

摘要： An engine valve operating system is provided in which a roller in rolling contact with a valve operating cam of a camshaft is axially supported via a roller shaft on a roller support portion provided on a first rocker arm, a second rocker arm having a cylindrical boss portion pivotably supported on a support shaft and an arm portion extending from the boss portion and having a sliding surface that is in sliding contact with the roller shaft is operatively connected to an engine valve, and the position of either one of first and second rocker arm swing axes is changed within a plane perpendicular to the axis of the camshaft, wherein at least the roller support portion (38) of the first rocker arm (23) is disposed at a position that overlaps the second rocker arm (26A, 26B) in plan view. This can provide an engine valve operating system that enables the size thereof to be reduced in a direction along the axis of the camshaft.
