Image Number 3 for United States Patent #5732729.

A valve includes two outlet ports and two inlets communicating with a chamber and includes two valve seats. A membrane is secured in the chamber. Two plugs are slidably engaged in the inlets for engaging with the valve seats and each includes one end engaged with the membrane and the other end slidably engaged with a cap. Two springs are engaged between the plugs and the caps for balancing the membrane and the plugs. One of the plugs is forced to engage with the valve seat by water from the inlet when no water is supplied to the other inlet.
