    Abstract: An internal combustion engine having at least one cylinder with inlet and exhaust valves operated via rocker arms by respective cams carried by a single camshaft. The camshaft is connected to its drive by an eccentric linkage, the eccentricity of which is varied by a device responsive to engine speed, and is least at high speed. As engine speed falls, increasing eccentricity results in a relative advance of inlet valve closing time and relative retardation of exhaust and inlet valve opening times but little change in the timing of exhaust valve closure. The lift of the valves may be varied also if the rocker arm axes are movably mounted.

    Abstract translation: 具有至少一个气缸的内燃机，其具有通过由单个凸轮轴承载的相应凸轮通过摇臂操作的入口和排气门。 凸轮轴通过偏心联动器连接到其驱动器，该偏心联轴器的偏心由响应于发动机转速的装置而变化，并且至少在高速下。 随着发动机转速的降低，偏心率的增加导致进气阀关闭时间的相对提前和排气门和进气阀打开时间的相对延迟，而排气门关闭时间几乎没有变化。 如果摇臂轴可移动地安装，则阀的升程也可以改变。

    Abstract: A continuous variable valve duration apparatus may include a camshaft, a first and second cam portions, first and inside brackets transmitting rotation of the camshaft to the first and second cam portions respectively, a slider housing of which the first and second inside brackets are rotatably inserted thereto, cam caps of which each cam cap engaging portion is rotatably connected thereto, a connecting bracket connecting the cam caps and of which a guide opening for the guide protruded portion to be inserted thereto for guiding movement of the slider housing is formed thereto, a slider pin rotatably inserted into the first sliding opening and slidably inserted into the camshaft, a cam pin of which a cam opening for the cam to be slidably inserted thereto is formed and rotatably inserted into the second sliding opening and a controller selectively changing a position of the slider housing.

    Abstract: A valve opening and closing timing control apparatus includes a driving-side rotating body, a driven-side rotating body fixed to a camshaft by a bolt, a fluid pressure chamber, an intermediate lock mechanism, a lock flow passage bringing the working fluid to the intermediate lock mechanism, and an electromagnetic valve including a spool which is arranged at an inner portion of the bolt, the lock flow passage including a first flow passage which is arranged between the spool and a supply flow passage in a radial direction and which is connected to the supply flow passage, the lock flow passage including a second flow passage which is provided at the inner portion of the bolt in a penetrating manner in the radial direction and which brings the working fluid to flow between the spool and the intermediate lock mechanism.
