    • The present invention provides a valve operating system for internal combustion engines, having a roller rolling contacting a valve operating cam, the system being provided with an oil supply passage capable of reducing a pressure loss to a low level even when a flow rate of lubricating oil entering the oil supply passage increases in accordance with a heightened engine speed, improving the lubricating ability with respect to the roller, and attaining a long lifetime of a rocker arm. This valve operating system includes a rocker arm support member provided with an oil passage in an inner portion thereof, a cam shaft provided on a valve operating cam, and a rocker arm which is provided with a roller rolling contacting the valve operating cam, and which is provided in an inner portion thereof with an oil supply passage for supplying a lubricating oil from the rocker arm support member to the roller, the sectional area of the flow passage of the oil supply passage increasing gradually from an opening thereof on the side of the roller toward an opening thereof on the side of the rocker arm support member.

    • In a valve operating system in an internal combustion engine, a swinging support section provided at a base end of a rocker arm is swingably carried on a rocker shaft mounted in a cylinder head. A plurality of valve abutments are provided at a tip end of the rocker arm and capable of being individually put into abutment against upper ends of a plurality of engine valves, and a cam abutment is provided on the rocker arm in an intermediate portion between the swinging support section and each of the valve abutments to come into contact with a valve operating cam. The swinging support section comprises a thinner cylindrical portion surrounding the rocker shaft, and thicker cylindrical portions which are formed at a thickness larger than that of the thinner cylindrical portion into a cylindrical shape to surround the rocker shaft and which are integrally and continuously provided at axially opposite ends of the thinner cylindrical portion, respectively. Thus, it is possible to enhance the durability of the rocker arm, while avoiding an increase in weight of the rocker arm.
    • 在内燃机的阀操作系统中,设置在摇臂的基端的摆动支撑部可摆动地承载在安装在气缸盖中的摇臂上。 在摇臂的前端部设有多个阀抵接部,能够分别与多个发动机气门的上端抵接,在摇臂上设置有摆动的中间部, 支撑部分和每个阀基座与阀操作凸轮接触。 摆动支撑部分包括围绕摇杆轴的较薄的圆柱形部分和较厚的圆柱形部分,该圆柱形部分的厚度大于较薄圆柱形部分的厚度,成圆柱形,以围绕摇杆轴,并且在轴向上一体地连续地设置 较薄的圆柱形部分的相对端。 因此,可以在避免摇臂的重量的增加的同时提高摇臂的耐久性。

    • A valve operating system in an internal combustion engine includes a switchover pin which is movable between an associatively operating position where adjacent ones of rocker arms are operated in association with each other, and an associative-operation releasing position where the associative-operation is released, the switchover pin receiving at axially opposite ends thereof a hydraulic pressure force acting toward the associatively operating position and a spring force acting toward the associative-operation releasing position, a cylindrical roller shaft which is fixed to one of the adjacent rocker arms, and into which the switchover pin is slidably fitted in response to the movement thereof toward the associatively operating position, and a roller rotatably carried on the roller shaft to come into rolling contact with a cam provided on a camshaft. In this valve operating system, at least one of axially opposite end surfaces of the roller shaft formed of a material harder than that of the one rocker arm, which receives the switchover pin, protrudes from a side surface of the one rocker arm. Thus, a wear powder can be prevented from entering into the roller shaft, thereby ensuring the smooth switching-over operation of the switchover pin.
    • 一种内燃机的气门操作系统,具备切换销,该切换销可以在相邻的摇臂相互联动的相关操作位置和在关联操作被释放的联动操作释放位置之间移动, 所述切换销在其轴向相对的端部处接收作用于所述关联操作位置的液压力和朝向所述关联操作释放位置作用的弹簧力;圆柱形辊轴,其固定到相邻的摇臂之一,并且其中 所述切换销可响应于其向所述关联操作位置的移动而可滑动地安装,以及可转动地承载在所述滚轴上的滚子以与设置在凸轮轴上的凸轮滚动接触。 在该气门操作系统中,滚子轴的轴向相对端面中的至少一个由与摇臂相当的一个摇臂形成的材料形成,所述摇臂接收切换销,从一个摇臂的侧面突出。 因此,可以防止磨损粉末进入辊轴,从而确保切换销的平滑切换操作。
