    • An infinitely variable transmission in which the pitches of a driving pulley and a driven pulley are variable by means of hydraulic fluid pressure to vary the velocity ratio between the two pulleys. A lower pressure fluid and a higher pressure fluid are created from a hydraulic fluid from a hydraulic fluid supply source, with a constant pressure difference therebetween. The lower pressure fluid has its pressure value varied in response to the velocity ratio. The lower pressure fluid and the higher pressure fluid are selectively supplied to the movable pulley elements of the driving pulley and driven pulley. A hydraulic clutch and a pressure regulating valve are connected together by a hydraulic fluid supply passageway which is selectively closed and opened by a supply control valve. A drain passage is connected to the hydraulic fluid supply passageway to allow hydraulic fluid to escape from the hydraulic clutch when the passageway is closed by the supply control valve. In at least one movable pulley element, an orifice is formed through a sealing element which seals between an inner peripheral surface of a cylindrical portion and a radially extending annular flange of a stationary piston element to communicate between first and second hydraulic pressure chambers defined within an annular space in a pulley main body at opposite sides of the annular flange of the stationary piston element.
    • 无级变速器,其中驱动滑轮和从动皮带轮的间距通过液压流体压力变化,以改变两个滑轮之间的速度比。 来自液压流体供应源的液压流体产生较低压力的流体和较高压力的流体,其间具有恒定的压力差。 低压流体的压力值随速度比而变化。 选择性地将低压流体和高压流体供给到驱动滑轮和从动滑轮的可动滑轮元件。 液压离合器和压力调节阀通过由供给控制阀选择性地关闭和打开的液压流体供给通道连接在一起。 排出通道连接到液压流体供应通道,以在通道由供给控制阀关闭时允许液压流体从液压离合器逸出。 在至少一个可动滑轮元件中,通过密封元件形成孔口,所述密封元件在圆柱形部分的内圆周表面和固定活塞元件的径向延伸的环形凸缘之间进行密封,以在限定在其内的第一和第二液压室之间连通 在固定式活塞元件的环形凸缘的相对侧的滑轮主体中的环形空间。
