ABSTRACT:
A liquid dispensing apparatus contains a mixing chamber, a communication chamber and a shuttle valve movable within these chambers which can be used to mix hot and cold water. A conduit operated by a three-way valve and connected to either the hot or cold water source communicates with the communication chamber by an orifice directly opposite from the mixing chamber. The shuttle valve contains one face which is exposed to the liquid flowing from the mixing chamber and a second face, having a surface area larger than said first face, exposed to the liquid flowing through the conduit. Due to the larger surface area on the second face, the shuttle valve will move to close the mixing chamber when a liquid is flowing through the conduit.
