摘要： The transmission comprises a hydraulic power transmission device, a V-belt stepless shifter and a planetary gear train. At restart time when the vehicle is at rest with the V-belt stepless shifter in high gear, the hydraulic power transmission device is operated to shift for providing a relatively high torque ratio, rather than the V-belt stepless shifter. A smooth restart is thus made possible. In addition, the planetary gear train permits the shifter smoothly to switch between forward and reverse. Both features meet the transmission needs of all vehicles.
摘要翻译：变速器包括液压动力传动装置，V形带无级变速器和行星齿轮系。在车辆处于高档档位的V型带无级变速器停转的重启时，为了提供相对较高的扭矩比，液压动力传递装置而不是V型带无级变速器而动作。因此，平稳的重启是可能的。此外，行星齿轮系允许变速器平稳地在正向和反向之间切换。两种功能都能满足所有车辆的传动需求。

摘要： In an hydraulic control system for an automatic transmission of a vehicle, when a low range frictional engagement mechanism is engaged in response to shift-down operation of the transmission, a flow regulator valve serves to steplessly regulate flow of fluid from a source of line pressure to the low range frictional engagement mechanism in accordance with changes of travel speed of the vehicle.
