    • To permit placing an electrical-hydraulical controlled automatic transmission, selectively, in reverse or neutral position upon failure of the control or command system, a spool valve is interposed between a fluid pressure pump and the control unit, the spool valve having three positions in which it can be placed manually; one of the positions is its normal operating position in which the valve provides a straight fluid path for pressurized fluid from the pump to the control unit; the other two positions are operable under emergency conditions, a second position providing a connection directly from the valve to the hydraulic servo units associated with control of the reverse gear, and the third interrupting suppply of hydraulic fluid from the pump to the control unit so that the control unit will, effectively, be placed in neutral position.
    • 为了允许在控制或命令系统故障时选择性地将电液压控制的自动变速器置于反向或中立位置,滑阀被插入在流体压力泵和控制单元之间,滑阀具有三个位置 它可以手动放置; 其中一个位置是其正常操作位置,其中阀提供用于从泵到控制单元的加压流体的直的流体路径; 另外两个位置在紧急情况下可操作,第二位置提供从阀门直接连接到与倒档齿轮的控制相关联的液压伺服单元的连接,以及液压流体从泵到控制单元的第三次中断,使得 控制单元将被有效地置于中立位置。
