Abstract
A mixing valve system for hot and cold liquids. A selectable temperature is controlled by mixing suitable parts of hot and cold liquid controlled by a plurality of disks having holes therethrough oriented in a particular manner to achieve the desired result. The system is composed of three stationary disks and two rotatable disks. Each rotatable disk is sandwiched between different pairs of the stationary disks. One rotatable disk controls the volume of flow and the other rotatable disk controls the amount of hot liquid that is to be mixed with the cold liquid.
