    • A diverter valve has an IN port (33) and first and second OUT ports (35,37) which are positioned along an arcuate path. A rotor (20) has an external control knob and a stem extending within the cavity of the valve body. Mounted an the stem, at right angles thereto, is a closure pin (23) which extends into the bore (15) of the hub (14) of a mushroom-shaped closure element (10). The surface of the domed head of the closure element is in contact with an O-ring seal (51) at one of the OUT ports. When the rotor (20) is turned, the O-ring (51), in contact with the surface of the domed head (12), cams the closure element (10) inwardly causing the element to slide inwardly on the closure pin (23). When the closure element (10) is in place to close-off one of the OUT ports, the other OUT port is opened and the pressure off the water flowing through the valve exerts a direct pressure on the flat annular undersurface (59) of the head of the closure element thereby maintaining the closure element in tight contact with the O-ring seal (51).
    • 分流阀具有沿着弧形路径定位的IN端口(33)和第一和第二OUT端口(35,37)。 转子(20)具有外部控制旋钮和在阀体的空腔内延伸的杆。 与杆成直角安装一个杆,它是一个延伸到蘑菇形封闭元件(10)的轮毂(14)的孔(15)中的封闭销(23)。 封闭元件的圆顶形头部的表面与其中一个OUT端口处的O形密封圈(51)接触。 当转子(20)转动时,与圆顶形头部(12)的表面接触的O形环(51)向内凸起封闭元件(10),导致元件在封闭销(23)上向内滑动 )。 当封闭元件10位于关闭其中一个OUT端口的位置时,另一个OUT端口打开,并且流过阀的水的压力施加直接压力到所述输出端口的平坦环形下表面(59) 从而保持封闭元件与O形密封圈(51)紧密接触。
