请查阅图1至图12，尤其是图2、图4、图8，所述止位机构300包括一径向滑动连接在主体110的滑动槽115的定位销310、一能够锁接在主体110的滑动槽115的外端口的塞子320和一顶抵在定位销310和塞子320之间的弹簧330，所述定位销310受弹簧330弹力作用在分水体200的外棘齿250，使得分水体200能够正转，无法反转。
请查阅图1至图12，尤其是图2、图4、图6，所述传动轴400，它转动装接在固定单元100，并转动穿过上盖120，并具有一控制端和一传动端，所述控制端位于上盖120之上，所述传动端位于上盖120之下。
请查阅图1至图12，所述摇杆600固接在传动轴400的控制端以能够带动传动轴400转动。
请查阅图1至图12，尤其是图2、图4、图6，所述离合机构，它连接在传动轴400的传动端和分水体200的内回转面之间，用于使传动轴400正转时处于合闭状态，传动轴400反转时处于分离状态。所述离合机构包括一凹设在传动轴400传动端并贯穿的装配槽710、一设在装配槽710之内的弹性体720和二滑动连接在装配槽710、分别连接在弹性体720二端并受弹性体720顶抵并伸出传动端的拨动块730，所述拨动块730适配于分水体200的内棘齿240。
请查阅图1至图12，尤其是图3、图8、图10，所述复位弹性体500为扭簧。所述传动轴400最好为下大上小的阶梯杆，所述扭簧500的一端连接顶抵在阶梯杆的阶梯面410，另一端连接在上盖120，则使得所述扭簧500不但能够产生扭矩使传动轴400反转复位，而且还能够产生一向下弹力作用在传动轴400，传动轴400将该弹力作用于分水体200，使得分水体200底面和主体110之间紧靠在一起，以实现密封性。最好，所述阶梯面之上凸设有一顶抵扭簧一端的台阶411。
根据需要，所述传动轴底面最好设置有凸点，用于减少接触面积，降低摩擦力。
请查阅图9、图12，本实施例之中，所述分水体200的出水孔230的出水面积最好大于分隔板113的相邻二分水孔114之间隔部分，但小于二个间隔部分和一分水孔之和，则使得所述出水状态包括三种，一为第一出水路，二为第二出水路，三为第一出水路和第二出水路。
为了使得审查员进一步了解本发明，下面具体介绍复位阀切换原理、复位原理：
假定原始状态中，所述分水体200处于第一位置，请查阅图8、图9，此时分水体200的出水孔230对齐分隔板113的第一组分水孔，此时第一出水路出水；
正转摇杆600，使得传动轴400正转，所述离合机构处于闭合状态，传动轴400带动分水体200正转，并转到第三位置，请查阅图10、图11，此时分水体200的出水孔230接通分隔板113的第二组分水孔，第二出水路出水；释放摇杆600，在扭簧500作用下，传动轴400反转复位，此时分水体200受止位机构作用固定，不跟随反转，离合机构处于分离状态；
依据上述描述，可由第二出水路切换至第一出水路和第二出水路，由第一水路和第二水路切换至第一出水路。
以上所述，仅为本发明较佳实施例而已，故不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。
工业实用性
本发明自动复位阀，结构简单、设计合理，能够实现自动复位，保证无论花洒处于何种状态，所述传动轴位于同一位置，便于用户操作，具有良好的工业实用性。
