    • A valve gear device includes a stem having one end and the other end, an intake and exhaust valve connected to the other end of the stem and serving for opening and closing a port formed in a cylinder block of an internal combustion engine, a first spring biasing the stem toward a closing condition of the intake and exhaust valve, a cam, and a valve control device interposed between the cam and one end of the stem, the valve control device having a first member fitted in the cylinder block so as to be slidable along an axis of the stem and engaged with the cam, a second member receiving one end of the stem and movable within the first member relative thereto and a regulating device for permitting and preventing the movement of the second member relative to the first member. Such a structure enables that the top end of the stem is out of sliding engagement with any of related members, thereby preventing a friction wear of the top end of the stem.
    • 一种阀齿轮装置,包括具有一端和另一端的杆,连接到杆的另一端并用于打开和关闭形成在内燃机的气缸体中的端口的进气和排气阀,第一弹簧 将阀杆偏压到进气和排气阀的关闭状态,凸轮和插入在凸轮与阀杆的一端之间的阀控制装置,阀控制装置具有装配在气缸体中的第一构件,以便于 可沿着所述杆的轴线滑动并与所述凸轮接合,所述第二构件容纳所述杆的一端并相对于所述杆在所述第一构件内可移动;以及调节装置,用于允许和防止所述第二构件相对于所述第一构件的运动。 这种结构使得杆的顶端不与任何相关构件滑动接合,从而防止杆的顶端的摩擦磨损。

    • In a valve control device for an engine having a fuel supply means arranged in a suction passage, a valve arranged in an intake or exhaust passage, and a cam for driving the valve to open and close via a lifter, the lifter comprises a body which slides in a bore of a cylinder head of the engine, a cylinder arranged in the body and forming a sliding passage perpendicularly to an axial direction of the valve, a spool which is transferred between a first position and a second position in the sliding passage by hydraulic pressure, a slider arranged in the spool and having a driving force transmitting portion and a cavity portion, and a spring which holds the spool at the first position, and a stop valve is arranged between the fuel supply means and the valve in the suction passage in order to close the suction passage when the spool is at the first position. When the spool is held at the second position, the driving force of the cam is transmitted to the valve only via the body and the driving force transmitting portion of the slider, and never transmitted to the spool. Thus, a stabilized change-over operation of the valve control device is achieved.
    • 在具有布置在吸入通道中的燃料供应装置的发动机的阀控制装置中,配置在进气或排气通道中的阀和用于驱动阀通过升降机打开和关闭的凸轮,所述升降机包括主体, 在发动机的气缸盖的孔中滑动,缸体布置在主体中并且形成与阀的轴向垂直的滑动通道;滑阀,其在滑动通道中的第一位置和第二位置之间传递;滑阀 液压,布置在所述卷轴中并具有驱动力传递部分和空腔部分的滑块以及将所述卷轴保持在所述第一位置的弹簧,并且在所述燃料供给装置和所述抽吸中的所述阀之间布置有截止阀 通道,以便当线轴处于第一位置时关闭吸入通道。 当阀芯保持在第二位置时,凸轮的驱动力仅通过滑块的主体和驱动力传递部分传递到阀,并且不会传递到阀芯。 因此,实现了阀控制装置的稳定的转换操作。
