    • A variator for ratio adjustment of a continuously variable chain drive transmission having one variator shaft (1) and one variator pulley (2) supported upon the variator shaft (1) and axially movable by pressurizing a variator pressure chamber (31). The variator shaft (1) has on one end an axial hole (10) through which the variator pressure chamber (31) and a second pressure chamber (8) can be loaded with pressure independent of each other. The pressure is supplied to the variator pressure chamber (31) via a first section (13) of the axial hole (10) and the pressure is supplied to the second pressure chamber (8) via a non-rotating pipe (7) and a second section (15) of the axial hole (10), the pipe (7) is situated within the first hole section (13). It is proposed that the pipe (7) has two axially adjacently disposed sealing rings (73) for reciprocal dynamic sealing of the pressure supplies to the variator pressure chamber (31) and to the second pressure chamber (8) and that the variator shaft (1) has a vent hole (9) discharging, on one side between the two sealing rings (73) and on the other side in a transmission inner space (94).
    • 一种变速器,用于具有一个变速器轴(1)和一个变速器滑轮(2)的连续变速链传动变速器的比例调整,所述变速器轴(1)和一个变速器滑轮(2)支撑在变速器轴(1)上并可通过加压变速器压力室(31)而轴向移动。 变速器轴(1)在一端具有轴向孔(10),变压器压力室(31)和第二压力室(8)可以通过该轴向孔(10)彼此独立地加载压力。 压力通过轴向孔(10)的第一部分(13)供应到变换器压力室(31),压力通过非旋转管(7)和第二压力室 所述轴向孔(10)的第二部分(15),所述管道(7)位于所述第一孔部分(13)内。 提出了管道(7)具有两个轴向相邻设置的密封环(73),用于将压力供给到变压器压力室(31)和第二压力室(8)的动态密封以及变换器轴 1)具有在两个密封环(73)之间的一侧上并且在变速器内部空间(94)中的另一侧上排放的排气孔(9)。
