    • There is disclosed a fluctuation torque cancellation apparatus which positively cancels a torque fluctuation developing on an input shaft or an output shaft of a motion conversion apparatus for converting a continuous rotational motion of the input shaft into a predetermined-type rotational motion (e.g. intermittent rotational motion) of the output shaft. A torque compensation cam 5, fixedly mounted on a rotation shaft 4, continuous rotates when the rotation shaft 4 rotate, and a cam surface, formed on a peripheral surface of the torque compensation cam 5, reciprocally moves a slider 7 in a cylinder 9 while rotating a cam follower 6. As a result, a coil spring 12, mounted within the cylinder 9, is compressed and expanded, so that a pressing force of the cam follower 6 against the torque compensation cam 5 is varied, thereby cancelling a fluctuation torque applied to the rotation shaft 4, thus effecting a torque compensation for the motion conversion apparatus 2. When it is desired to vary the torque compensation value, the air is supplied from an air source 16 to an air chamber 17 in the cylinder 9 to add a pressing force by the air, so that the compensation torque is exerted on the rotation shaft, using both of the spring pressure and the air pressure.

    • The invention relates to a device (100') for actuating at least one valve (4) in an internal combustion engine. The device comprises a camshaft arrangement (200') comprising a hollow outer shaft and an inner shaft, which is concentrically mounted inside of the outer shaft to be pivotable relative to the outer shaft. A first cam lobe (206) is mounted on one of the inner shaft and the outer shaft in a rotationally fixed manner and a second cam lobe (208) is mounted on the other of the inner shaft and the outer shaft in a rotationally fixed manner. The device further comprises a rocker arm arrangement (300') comprising a first primary rocker arm (302), which is arranged to follow the first cam lobe (206) and arranged to actuate a first valve (4) when it follows the first cam lobe. The rocker arm arrangement (300') further comprises an auxiliary rocker arm (306), which is arranged to follow the second cam lobe (208). The auxiliary rocker arm is adapted to actuate the first primary rocker arm (302) so that an opening time of the first valve (4) may be extended by the auxiliary rocker arm (306) following the second cam lobe (208).
    • 本发明涉及一种用于致动内燃机中的至少一个阀(4)的装置(100')。 该装置包括凸轮轴装置(200'),该凸轮轴装置(200')包括中空外轴和内轴,该内轴同心地安装在外轴的内部以相对于外轴枢转。 第一凸轮凸角(206)以旋转固定的方式安装在内轴和外轴中的一个上,并且第二凸轮凸角(208)以旋转固定的方式安装在内轴和外轴中的另一个上 。 该装置还包括摇臂装置(300'),该摇臂装置包括第一主摇臂(302),该第一主摇臂(302)布置成跟随第一凸轮凸角(206)并且布置成当第一阀(4)跟随第一凸轮 叶。 摇臂装置(300')还包括布置成跟随第二凸轮凸角(208)的辅助摇臂(306)。 辅助摇臂适于致动第一主摇臂(302),使得第一阀(4)的打开时间可以通过辅助摇臂(306)跟随第二凸轮凸角(208)延伸。 p>
