    • In a default device of an actuator for a variable lift valve operating mechanism, in the event of failure of the actuator, a pressed portion of a lever pivotably supported on a support shaft is urged by a resilient force of a coil spring, an arm is pressed by a cam portion of the lever to rotate a control shaft in one direction to prevent valve lift from being a predetermined value or lower. The support shaft that pivotably supports the lever of a default mechanism is placed in a position offset from a rotation axis of the control shaft. Thus, as compared with the case where the support shaft is placed coaxially with the control shaft, a large urging force is input from the lever to the control shaft to reliably prevent the valve lift from being the predetermined value or lower.
    • 在用于可变提升阀操作机构的致动器的默认装置中,在致动器发生故障的情况下,可枢转地支撑在支撑轴上的杠杆的按压部分被螺旋弹簧的弹力推动,臂是 由杠杆的凸轮部分按压以使控制轴沿一个方向旋转,以防止气门升程达到预定值或更低。 可枢转地支撑默认机构的杠杆的支撑轴被放置在偏离控制轴的旋转轴线的位置。 因此,与支撑轴与控制轴同轴配置的情况相比,从杠杆向控制轴输入大的作动力,可靠地将气门升程降低到规定值以下。

    • A sheet-fed offset rotary printing press with a convertible press mechanism includes a chucking cylinder, convertible cylinder, grippers, and air nozzles and blowing ports. The chucking cylinder conveys a sheet by holding its leading edge. The convertible cylinder is arranged downstream of the chucking cylinder in a sheet convey direction and holds a trailing edge of the sheet being conveyed by the chucking cylinder. The grippers cause the convertible cylinder to hold the sheet in a turned state when the sheet is to be transferred from the chucking cylinder to the convertible cylinder. The air nozzles and blowing ports are arranged at different heights on outer sides of two ends in a widthwise direction of the sheet, and blow air toward a center in the widthwise direction of the sheet which is turned over by the grippers, so as to separate the sheet from the chucking cylinder.
    • 具有可转换压力机构的单张纸偏移旋转印刷机包括夹紧圆筒,可转动圆筒,夹具,空气喷嘴和吹风口。 夹紧圆筒通过保持其前缘来传送片材。 可转动缸体在片材输送方向上设置在夹紧缸的下游,并且保持由夹紧缸传送的片材的后缘。 当纸张从夹紧缸传送到可转动缸时,夹具使得敞篷车把纸保持在转动状态。 空气喷嘴和吹气口在片材的宽度方向上的两端的外侧上设置在不同的高度,并且通过夹子向片材的宽度方向的中心吹送空气,以分离 来自吸盘的片材。
